Question

Ketone on reduction gives:

• A. \( \text{Primary alcohol} \)
• B. \( \text{Secondary alcohol} \)
• C. \( \text{Aldehyde} \)
• D. \( \text{Carboxylic acid} \)

Hint:

Reduction reactions of ketones are widely used in organic synthesis to generate alcohol-based intermediates.

Answer 1

The Correct Option is B

Ketones undergo reduction via agents such as LiAlH\(_4\) or NaBH\(_4\) to form secondary alcohols. This reaction follows: \[ R_2C=O + H_2 \rightarrow R_2CH-OH \] Unlike aldehydes, which reduce to primary alcohols, ketones yield secondary alcohols due to the absence of a hydrogen atom on the carbonyl carbon.
