Reduction of two different carboxylic acid derivatives with LiAlH₄ would give the amine shown. Identify these carboxylic acid derivatives.

검증된 단계별 안내

Understand that LiAlH₄ (Lithium aluminum hydride) is a strong reducing agent commonly used to reduce carboxylic acid derivatives to alcohols or amines.

Recognize that the reduction of carboxylic acid derivatives to amines typically involves the conversion of amides or nitriles.

Consider that amides (RCONH₂) can be reduced by LiAlH₄ to primary amines (RCH₂NH₂).

Consider that nitriles (RCN) can also be reduced by LiAlH₄ to primary amines (RCH₂NH₂).

Identify that the two carboxylic acid derivatives that can be reduced to the same amine are likely an amide and a nitrile, both having the same carbon skeleton as the resulting amine.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Carboxylic Acid Derivatives

Carboxylic acid derivatives are compounds that can be converted into carboxylic acids through hydrolysis. They include esters, amides, anhydrides, and acyl chlorides. Understanding their reactivity and transformation is crucial for predicting the products of reduction reactions.

Reduction with LiAlH₄

Lithium aluminum hydride (LiAlH₄) is a strong reducing agent used in organic chemistry to convert carboxylic acid derivatives into alcohols or amines. It is particularly effective in reducing esters and amides to primary alcohols and amines, respectively, by breaking the carbon-oxygen or carbon-nitrogen bonds.

Amine Formation

Amines are organic compounds derived from ammonia by replacement of one or more hydrogen atoms with organic groups. In the context of reduction, amines can be formed from amides or nitriles when treated with LiAlH₄, which reduces the carbonyl group to a methylene group, resulting in the formation of primary amines.
