Question

The Wolff-Löffler-Kishner reduction is used to convert which of the following compounds into the corresponding alkane?

• A. Aldehydes
• B. Alcohols
• C. Ketones
• D. Carboxylic acids

Hint:

The Wolff-Löffler-Kishner reduction is a useful method for converting carbonyl compounds, particularly ketones, into alkanes. Be sure to remember the role of hydrazine and a strong base in the reaction.

Answer 1

The Correct Option is C

The Wolff-Löffler-Kishner reduction is a reaction used to reduce carbonyl compounds (like aldehydes and ketones) to the corresponding alkanes. In this reaction, a ketone is treated with hydrazine (H\(_2\)N-NH\(_2\)) in the presence of a strong base (usually potassium hydroxide) under heating conditions. This results in the elimination of the carbonyl group, converting the compound into an alkane. - Option (A) is incorrect because although aldehydes can undergo similar reductions, the question specifically refers to ketones as the correct reactant for the Wolff-Löffler-Kishner reduction.
- Option (B) is incorrect because alcohols are not typically involved in this reduction.
- Option (D) is incorrect because carboxylic acids require a different type of reduction process, such as the reduction to aldehydes using stronger reagents. Therefore, the correct answer is option (C).
