Question

Which of the following compounds contains $-OH$ functional group?

• A. Propanone
• B. Propanol
• C. Propanoic acid
• D. Propanal

Answer 1

The correct option is B Propanol

In propanone, the functional group present is a ketone ($-\underset{|}{C}=O$) group as the suffix is one.

In propanol, the functional group present is a alcohol ($-OH$) group as the suffix is alcohol.

In propanoic acid, the functional group present is a carboxylic acid (COOH) group as the suffix is oic acid.

In propanal, the functional group present is an aldehyde ($-CHO$) group as the suffix is al.

So the compound containing $-OH$ functional group is propanol.

Hence the answer is option B
