The reagent which can do the conversion \(\mathrm{CH}_{3} \mathrm{COOH} \longrightarrow \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{OH}\) is
- A \(\mathrm{LiAlH}_{4} /\) ether
- B \(\mathrm{H}_{2}, \mathrm{Pt}\)
- C \(\mathrm{NaBH}_{4}\)
- D Na and \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{LiAlH}_{4} /\) ether
Step-by-step Solution
Detailed explanation
\(\mathrm{LiAlH}_{4} / \mathrm{ether}\) is an reducing agent, thus it can reduces carboxylic acid (in this case is acetic acid) to alcohols (in this case is ethanol). The overall reaction is as follows
\(\mathrm{CH}_{3} \mathrm{COOH} \stackrel{\mathrm{LiAlH}_{4} / \text { ether }}{\longrightarrow} \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\)
\(\mathrm{CH}_{3} \mathrm{COOH} \stackrel{\mathrm{LiAlH}_{4} / \text { ether }}{\longrightarrow} \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\)
