Reduction of a ketone with sodium borohydride or lithium aluminium hydride gives
- A. a primary alcohol
- B. a carboxylic acid
- C. a secondary alcohol
- D. an alkane
Explanation
The hydride ion adds to the carbonyl carbon, which then carries two alkyl groups and a hydroxyl, so the product is a secondary alcohol. An aldehyde reduced in the same way gives a primary alcohol. Reduction is simply the reverse of the oxidation that produced the carbonyl compound in the first place.
