I think the biggest requirement for Sn2 is having a primary electrophile.
A triglyceride is your lipid, your classic energy storage that the body uses. If you can plug everything back into the mechanism, you will be much more likely be able to apply it correctly under pressure on test day as opposed to having memorized generic stuff in the abstract.
Both of them have hydrogen bonding so you can throw out both choices (A) and (B) together because if it were H2O then methanol would be the same answer as they both behave the same way. © Medical School Headquarters - All Rights Reserved. For SN2, remember the backside attack. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. Looks like you're using new Reddit on an old browser. Ah thanks for clarifying it. Although similar , I would consider nucleophilic acyl substitution it’s own type of reaction. Now, we just have to decide between acetone and toluene. The key to understanding this is starting with the mechanism itself. Press question mark to learn the rest of the keyboard shortcuts.
Why would a methyl or a primary carbon favor a backside attack? You Need to Know This!]. 1 month ago. © Medical School Headquarters - All Rights Reserved.

SN1 SN2 E1 Series: Video 15 Knowing that your alkyl halide will undergo nucleophilic substitution is not enough. Learn vocabulary, terms, and more with flashcards, games, and other study tools. In SN2, with the inversion and changing the molecule from R-->S or vice-versa, wouldn't it produce the opposite degree of rotation, therefore = 0 degrees? From my understanding, with SN2, you start with a specific stereochemistry (either R or S) and the rxn will end up with the reverse stereochemistry due to back side attack. Idk if someone has already posted this on here but it gives a nice summary of Sn1 and Sn2 rxns.

For toluene, you wouldn’t even be able to dissolve the reagents because toluene is just a purely organic solvent. Please check your email for further instructions. Why Do You Want to Be a Doctor? Remember the nomenclature triglyceride, if you drew this, is E-shaped where there’s these big long tails making up the three prongs of the E. So that’s three fatty acid molecules and all of them are just plugged together in these little ester linkages to a glycerol backbone. Are nucleophilic acyl substitution reactions Sn1 or Sn2? SN2 is the classic backside attack.
And that’s because there is less stearic hindrance. Press question mark to learn the rest of the keyboard shortcuts. Start studying MCAT Substitution (SN1 & SN2) reactions.

As opposed to the SN1 mechanism, which is a two-step process, where first the living group just leaves. But it is similar to an SN2 reaction since an SN1 reaction would always have the leaving group leave in the first step where as in nucleophilic acyl substitution the first step is the nucleophile attacking the electrophile and then the pi electrons jumping up to the oxygen. Simple math. Although similar , I would consider nucleophilic acyl substitution it’s own type of reaction. Thanks for subscribing! The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical schools in the USA and Canada. It’s totally on its own and forms the carbocation intermediate.
Which is kind of analogous to an SN2 reaction where also a nucleophilic attacks an electrophile and instead of breaking a pi bond and then reform the pi bond and then break a sigma bond, it would just break a sigma bond right away. The nucleophile comes in, attacks the carbon, and kicks off the living group all in a single step. Just google SN1 versus SN2 and you will find a million charts out there. 1.
