Question

• When Ethylmethyl ketone undergoes wolf-
kishner reduction gives
Answer
A.Ethane
B. Acetaldehyde
C. Butane
D. 2-Butanol​

Answer 1

Butane is the answer.

Explanation:

$ch \frac{}{3} ch \frac{}{2} coch \frac{}{3} - - > ch \frac{}{3} ch \frac{}{2} ch \frac{}{2} ch \frac{}{3}$Wolf kishner reduction is the process in which carbonyl compounds when heated with hydrazine followed by potassium hydroxide gives the corresponding alkane. Carbonyl group is reduced to alkyl group. here ethyl methyl ketone or pentan-1-one when produced using wolf kishner reduction process, carbonyl group is reduced to alkane group and we get butane as a final product.

Answer 2

Wolf Kishner reduction of ethyl methyl ketone will yield butane

• Wolf Kishner reduction is a type of reduction reaction in which aldehyde and ketone groups get reduced to form alkanes/ hydrocarbons.
• In this reaction, aldehyde/ketone is first treated with hydrazine followed by potassium/sodium hydroxide in ethylene glycol to convert them into alkanes.
• Wolf Kishner reduction of ethyl methyl ketone will take place as follows:

CH₃COCH₂CH₃ + NH₂NH₂ → CH₃C=NNH₂CH₂CH₃ + KOH +ethylene glycol → CH₃CH₂CH₂CH₃ + N₂

Thus, when Ethylmethyl ketone undergoes Wolf-Kishner reduction it gives (Option C) Butane.
