Question

The most suitable reagent used for converting ethanoic acid to ethanol is_________.

• A. $LiAl{H}_4$
• B. $B{H}_3$
• C. $PC{l}_3$
• D. $K_{2}C{r}_2{O}_7/H^{+}$

Answer 1

The correct option is A $LiAl{H}_4$

The reagent used for converting ethanoic acid to ethanol is lithium aluminium hydride $\left(LiAl{H}_4\right)$. It is a reducing agent and reduces carboxylic acid to aldehydes and further to alcohols.

$B{H}_3$ is used for the hydroboration oxidation of alkene. $PC{l}_3$ converts carboxylic acids to acid chlorides and alcohols to alkyl halides.

Acidified potassium dichromate is an oxidizing agent which oxidizes alcohols to aldehydes and further to carboxylic acids.

Hence, option A is correct.
