Solution

The functional group -OH, also known as a hydroxyl group, is present in the compound Butanol. So, the answer is (b) Butanol.

Here's a step-by-step explanation:

  1. Butanone: This compound contains a carbonyl group (C=O) and is a type of ketone. It does not contain a hydroxyl group (-OH).

  2. Butanol: This compound contains a hydroxyl group (-OH) and is a type of alcohol.

  3. Butanoic acid: This compound contains a carboxyl group (-COOH), which does include a hydroxyl group, but the entire group is considered a carboxyl group, not a hydroxyl group.

  4. Butanal: This compound contains an aldehyde group (-CHO), not a hydroxyl group (-OH).

So, the compound among the given options that contains -OH as a functional group is Butanol.
