Is it worth the time trying to memorize NMR and IR signals?

[CherryBlossom1412]

What do you guys think? I feel like there's no way to memorize all the signals for NMR and IR. ((( Is this topic very important on DAT?

it showed up on my version. I had 2-3 questions on it. It was pretty straightforward though. I suggest making flashcards for the most common signals like carbonyl signals and -OH signals ect. HNMR is pretty important too and CNMR. All showed up on mine.

 

[DMikes]

Know common ones. I wouldn't emphasize it too much.

IR yes, NMR no

as you progressively do OC practice, it'll get repetitive and you'll memorize most of the signals. Destroyer has plenty of these questions and you get use to them. These questions are easy points in my opinion

Yes, indeed. NMR, IR, and lab techniques are an integral part of Organic Chemistry and will be tested on the DAT. I have put in DESTROYER all the tests, and numerical Spectroscopic " landmarks " that you will need to know.

Yes, I had to identify both NMR & IR on my exam just a couple days ago.

NRM - I was given just signals in numbers
IR - I was given an actual graph

yes. use chad's videos to learn what you should know for these topics. then do destroyer problems

 

[averageasian]

practice the questions on destroyer and youll be good. Also, on one of the bootcamp tests, there was a question on NMR and dr. Mike does an awesome video on NMR and it helped me understand it.

Yes! I had 2-3 question on my DAT on these topics

oh thanks so much! I bought math and dat destroyer and i just finished reviewing ochem so I'll start the practice test now

 

[WheatLom]

yep, both are major components to laboratory OC.

Good luck to you!

I had zero questions on it, but unfortunately it's not always like that

Agree, not always like that..

+1 for Mike's videos with this. Going through destroyer, I have been able to get all of the NMR and IR questions right and I really don't know exactly the numbers where things appear.

I've just been remembering that higher energy groups cause things to move to the left with NMR and a few little facts with IR. You definitely don't need to memorize the huge tables of what everything means. Mike's videos does a great job of minimizing the things you need to remember.

I don't know what you mean by higher energy groups, but just remember the double Ds. Downfield = deshielded = electron-withdrawing.

You're right, bad description on my part. What I mean by that is mostly relating to ketones, aldehydes, and carboxylic acids. The C or H NMR for those groups are to the left.
