1

What is the product of a Wolff-Kishner reduction?

Wolff-Kishner reduction:

2

Which of the following statements is correct about addition reactions of hydrogen cyanide to carbonyls?

Addition of HCN:

3

What is the product of a Wittig reaction?

Wittig reaction:
 

4

Which of the following statements is correct about Wittig reaction?

Wittig reaction:

5

What is the product of a Baeyer-Villiger oxidation?

Baeyer-Villiger Oxidation:
 

6

Which of the following alkyl substituents migrates the fastest in a Baeyer-Villiger reaction?

With asymmetric ketones, esters can be selectively formed by migration of only one of the substituents. Migratory aptitudes in the Baeyer-Villiger reaction: Methyl  <  Primary Alkyl < Phenyl ~ Secondary Alkyl < Tertiary Alkyl

7

In the formation of imines from aldehydes and ketones, which component acts as the nucleophile?

Amines act as nucleophiles because they have a lone pair of electrons on the nitrogen atom, which can attack the partially positive carbonyl carbon, leading to imine formation.

8

What is the major difference in the outcome when comparing the Wolff-Kishner reduction to hydride addition to the carbonyl of an aldehyde?

Wolff-Kishner reduction specifically converts a carbonyl compound into a hydrocarbon by removing oxygen as water, whereas hydride addition to an aldehyde produces an alcohol.
