Random Facts for MCAT

[starbaduk]

Some random stuff I wrote down on my notes as I was studying for the MCAT. Thought I'd share with you guys. Highlight the area below the question for the answer. Feel free to add

Unsaturation in alkene increases or decreases viscosity?

Decreases

Difference between regioselectivity and stereoselectivity?

For example, hydrogenation of alkene via H2/Ni is stereoselective but not regioselective. Since hydrogenation is cis, it's stereoselective. But since both carbons receive hydrogens, it's not regioselective.


Adding dielectric stuff between the capacitor plates increases or decreases the capacitance?

Increases

Iodoform reaction (I2/Oh-) tests for what functional group?

Methyl Ketone


Solubility: Cl-, Br-, I- ions are soluble except for?

Ag+, Hg2++, Pb++

What happens to carbonyl in Wittig reaction?

C=O bond is replaced with C=CRR' bond

Naturally occurring amino acids are L or D?

L

Naturally digestible sugars are usually L or D?

D

Wolff-Kishner reduction (reagent N2H4) does what to carbonyl?

Replaces C=O bond with two C-H bonds

I'd like to modify what you answered for the Wittig reaction to 'repalces C=O with C=C-R.' It's not necessarily two H's.

Thanks much for pointing that out. I might have missed that question on the mcat!

... hey guys. can you explain these 2 to me? Thank ye!
