The Correct Option is A
Solution and Explanation
The given reaction is the reduction of acetic acid (CH₃COOH) to ethanol (CH₃CH₂OH).
Let's analyze each option:
- Option A: LiAlH₄ / ether: Lithium aluminum hydride (LiAlH₄) is a strong reducing agent that can reduce carboxylic acids to alcohols. The reaction with ether as the solvent is typical for this reduction, making this the correct choice.
- Option B: H₂, Pt: Hydrogen with platinum can reduce carboxylic acids to alcohols, but LiAlH₄ is more commonly used for this reduction.
- Option C: NaBH₄: Sodium borohydride (NaBH₄) is a milder reducing agent and can reduce aldehydes and ketones to alcohols, but it is not effective in reducing carboxylic acids.
- Option D: Na and C₂H₅OH: This combination does not serve as an effective reducing agent for carboxylic acids.
The correct answer is (A) : LiAlH4 / ether.
