What is the product formed on the reduction of carboxylic acids using lithium aluminum hydride?
- Correct answerAPrimary alcohol
- BSecondary alcohol
- CAldehyde
- DKetone
Solution
Lithium aluminum hydride ($LiAlH_4$) is a strong reducing agent.
It reduces carboxylic acids directly to primary alcohols.
The general reaction is:
$R-COOH \xrightarrow{LiAlH_4} R-CH_2OH$
Thus, the product formed is a primary alcohol.
