Question

The compound that forms when acetaldehyde reacts with $LiAl{H}_4$ is :

• A. $C_2{H}_{5}OH$
• B. $C{H}_{3}COOH$
• C. $C_2{H}_{5}O{C}_2{H}_5$
• D. $C{H}_{3}COOC{H}_3$

Answer 1

The correct option is A $C_2{H}_{5}OH$

$LiAl{H}_4$ when added to the carbonyl carbon of acetaldehyde generates ethanol (nucleophilic addition reaction).

When aldehyde reduced by $LiAl{H}_4$ produces primary alcohol while ketone reduced to a secondary alcohol.

Option A is correct.
