organic chemistry

Need some clarification for a neurotic pre med. I graduated in May 2015 and have just completed one semester of organic lab (paid 600$ out of pocket), which most schools have as an admission requirement/recommendation. However, the school which I took the lab at splits up Orgo lab into a year...

Hey everyone! I'm a little confused about the answer for question #122 in the organic chem section for the 2015 version. The answer says 1,3- dimethylcyclohexane has 3 stereoisomers. However, I can only think of two since the cis stereoisomers would be meso. The answer shows that the cis-wedge...

Hello, I am a 19 year old honors student and just finished my first semester of sophomore year. I graduated high school with over a 4.0 GPA. Depression, however, has had a big impact on me over the past few years. I have always wanted to be in the medical field, either as an MD or PA. I am now...

I'm a sophomore pre-med (just decided on the pre-med track.) My GPA's at a 3.6 right now bc I was pretty bad with time management last year, so I've been hoping to bump it up this semester. But I'm really worried about my O Chem lab grade. My TA is a really harsh grader. At first, I didn't...

Hi everyone! Im planning on taking the DAT this coming summer but i will be studying all summer and taking it at the end. I was curious as to what material i should be using? Based on previous standardized exams i'm not the best at english/reading comp. Im currently taking bio 1 now and will be...

I have to take Physics I & II over the summer or Orgo I & II to stay on track, so just in general which do yo guys think is worse to take over the summer. In summer I'll have to take physics labs so it's 5 credits in 5 weeks and another 5 for the second summer session. Organic chem lab is 2...

I am currently taking organic chemistry II, our prof said any book should be fine. I'm looking for a book that explains concepts well and has good built in problems. What do you think is good? Klein (2nd edition) Brown (7th edition) Janice Smith (2nd edition) Solomon Wade or any other...

Hey all, I am very hesitant to drop my organic chem 2 lecture however I feel like I need to because I am doing poorly in it. The whole class is actually not doing well partly due to a new professor who has a different style of teaching. Long story, short: his exams are extremely tough. I go to a...

I'm a sophomore at Tufts and I'm trying to figure out when to take orgo. I took gen chem last year and struggled with it. I ended up with a B in chem 1 and a C+ in chem 2 (although part of the reason was because I somehow idiotically skipped two pages on the final). I'm currently registered for...

From my (perhaps flawed) understanding... It seems like the same general factors govern nucleophilicity (kinetic term related to reaction rate) and basicity (thermodynamic term related to acid/base equilibrium position). Of course, the same molecule can act as either a nucleophile (nucleophilic...

The question asks which reagents would be best to make isobutanol into isobutyl chloride. "SOCl2, Pyridine" was the correct answer. I chose an answer that included that along with HCl, but apparently HCl is wrong. The solution says that a shift would occur with HCl to give 2-chloro-2-methyl...

So I take my OAT in one week and I am absolutely FREAKING out about the orgo section...the way that Kaplan words their questions confuses me so much. For those of you that have taken it recently, was it mainly reactions? Is it imperative to know the mechanisms? I've also never done NMR or IR...

Why are two alpha protons needed for a successful claisen reaction? After the initial enolate nucliopophile attacks an ester and does a addition elimination reaction what is the purpose of the second alpha proton?

Hey guys! Of you all who have taken the DAT, how often do IR/NMR spectroscopy problems show up? IR is pretty straight forward but NMR is kind of confusing and I don't really understand it. Any tips or links to helpful material would be appreciated!

My DAT is in a week and I'm freaking out especially for biology and chemistry. If I do all the bootcamp bio exams and read all the explanations and understand them, would I be in good shape for the actual bio on the dat? I got a 17 on my first and second bio exam on bootcamp, will this translate...

Would adding a deactivating or activating group speed up this reaction!? I know its not an EAS reaction and cant think "oh a donating group would cause it to react faster." I've also read a paper that said esters react similarly like amides and go quicker with electron withdrawing groups. Does...

I am selling these books as a bundle, but if you need one or two books, make me an offer. Used by my sister in law, but she ended up going to graduate school instead. They are all clean 1. 16 mini MCAT book - no marking in the book 2. 101 passages MCAT verbal reasoning - Very good condition...

Hey! :) First Question-- I'm aware that Chad is in some sort of dispute with course saver, but his videos are still on the course saver website. I wanted to purchase a 30 day subscription for his videos on course saver-- and tried multiple times to make a purchase-- but the website wouldn't let...

I'm finishing organic chemistry this quarter and will be taking biochemistry in the fall. Looking back, I know general principles of reactions (E2, E1, Sn1, Sn2, tetrahedral intermediates, etc.), but I don't remember certain reaction mechanisms. On top of that, for other reactions where we never...

Yes, I have went through prior posts regarding this. I'm taking Organic Chem I, Organic Chem I Lab, and Stats summer session 1. I'm taking Organic Chem II, Organic Chem II Lab, and Calc summer session 2. I've taken both the maths before. I'm simply trying to raise my sGPA/BCPM GPA. Do you have...

Edit: problem solved!

I need to get a 53% on the final to keep the grade I have. My professor said that 41/70 is a 78%, since that is the national average. Can anyone tell me what number (out of 70) would constitute a 53%? I really don't know much about this exam, and the percentiles / grading system, since my...

So I'm going to be taking organic chem I & II in the summer and since these are courses that are seen as tough will it be looked down on that I took them in summer? It's at the same university I'm attending and right now I'm taking 21 credits with 2 labs so there's no way my dean will allow me...

I have an 8-book set of The Berkeley Review (TBR) MCAT review books, 2013 edition, that I am selling. I have 2 biology books, 2 organic chemistry books, 2 general chemistry books, and 2 physics books. There is some writing in the content review parts, but the practice sections are clean with no...

Hi! 1. I am looking for some clarification of the relationship between these concepts. hydrophobic/hydrophilic non-polar/polar negatively charged/positively charged acidic/basic I understand that a molecule can be any of the above. But I am wondering how these are related. From my current...

When I did this problem I counted carbons and hydrogens etc. and used this variant of the formula #C + #N/2 + 1 - #H/2 - #X/2 The answer was 13, and it explained I can count 3 rings + 10 double bonds = 13 degrees of unsaturation. I will be using this method on a question like this, but somehow...

Hi everyone! I needed some advice on what pre-reqs are accepted by med schools. I am about to graduate with my biology degree and originally had planned to go to PA school, but had a change of heart recently and decided to pursue med school instead. Since I had not intended to apply to med...

Hi everyone, I am reviewing orgo basics and have been pretty confident about naming cycloalkanes. Until I came across the following problem. Name the following cycloalkane: My response was 1,3-dichloro-4,5-diethylcyclopentane. But the answer key says the correct response is...

Hello everyone! I am wondering if anyone has taken Orgo 2 online through the University of New England. What would you suggest or recommend as preparation for the exams and labs? Thanks!

Hi there, I am a Sophomore in College and I have to declare my major soon. So far I have just been doing the pre-requistes for med school and now I have to decide what I want to major in. I am deciding between Health Science and Economics. What do you think? What would yo chose and why ...

I go to a school that's on the quarter system. This fall I went abroad and took three quarters worth of the organic chemistry lectures (a year of organic chemistry lecture) and one quarter of the corresponding lab. I am currently completing the second quarter of the corresponding lab. Had I not...

Background: Appreciate any and all advice. I'm finishing up my bachelor's in a non-science major this Spring so I'm taking a year to finish pre-requisites and get some additional ECs. I'm going to take classes in all 3 summer, fall and spring semesters, but I'm also going to take the MCAT after...

nvm

Hi Everyone! I am looking at taking some science pre-reqs for med school, to make sure I can handle them and also to (hopefully) boost my undergraduate gpa. Has anyone taken the following courses online through Athabasca, and, if so, what are your thoughts on them? BIOL 204 & 205 - Principles...

I'm going to be applying to pharmacy schools this fall. I graduated with a BS in biology May 2015, and I've spent the last year taking the last few prereqs needed for pharmacy school (I decided to do pharmacy really late) and working as a pharm tech in a hospital. I'll be done with all my...

hey everyone! how much of Ochem 2 builds on o chem 1? The reason I'm asking is that I’m trying to decide if i should retake ochem 1, not necessarily to get a better grade (I got a C), but because if it builds into o chem 2 a lot, i would rather do o chem 1 again, just so I don't struggle in o...

I've always struggled with math and avoided it like the plague. I failed Precalculus and even basic Statistics was a daunting class for me. It's always been frustrating and ironic because chemistry's always come easy to me, and I breezed through both semesters of General and Organic Chemistry...
