NEET levelSingle correct optionDifficulty 1 of 3ap169

Which of the following reagents converts ethanoic acid, $CH X_{3} COOH$ , into ethanol?

A $NaBH X_{4}$ in ethanol
BTollens' reagent
C $LiAlH X_{4}$ in dry ether, then $H X_{3} O X^{+}$
D $PCC$ in $CH X_{2} Cl X_{2}$

Answer: C

Carboxylic acids are reduced to primary alcohols by the strong hydride donor

LiAlH X_{4}

.

NaBH X_{4}

is too weak to reduce acids, while Tollens' reagent and PCC are oxidising agents.
