Don T Forget to Study the Generic Functional Groups and the Common Alkyl Groups (Isobutyl, Etc)
ALCOHOLS & PHENOLS SOLUTIONS
Don’t forget to study the generic functional groups and the common alkyl groups (isobutyl, etc).
- IUPAC = I and common = c.

- This one is tougher. Note the addition of the ethyl group. The only methods we’ve learned for adding Carbon groups are 1) chain lengthening terminal alkynes, 2) FC alkylations/acylations to aromatics, 3) Grignards, organosodium and Gilman reactions. Obviously the first two don’t apply here, so look for an opportunity to perform a Grignard rxn, i.e., synthesize a carbonyl to add the Grignard to:
For the following reaction:
a)Write products for the reaction
b)Show the mechanism of the reaction
c)Calculate pKeq
This 3° alcohol is undergoing an SN1 reaction. OH is a poor leaving group, but once protonated by a strong acid, a better leaving group is formed (H2O).
