Which one of the following compounds is a ketone?
- A
CH3 ― O ― CH2 ― CH3
- B
CH3 ― CO ― CH2 ― CH3
- C
CH3COCOOH
- D
CH3 ― CH2CHO
Ketone has a general formula of R- CO-R, meaning that there are two radical groups surrounding a carbonyl group(C=0).This is shown in option B only. The radical group surrounds O in option A so it is either, not a ketone. Option C has a COOH group so it is a carboxylic acid. Option D has a CHO group, making it aldehyde.

The radical group surrounds O in option A so it is either, not a ketone. Option C has a COOH group so it is a carboxylic acid. Option D has a CHO group, making it aldehyde.p surrounds O in option A so it is either, not a ketone. Option C has a COOH group so it is a carboxylic acid. Option D has a CHO group, making it aldehyde.
This compound is an ether, not a ketone. Ethers have an oxygen atom bonded to two alkyl or aryl groups.

This compound is a carboxylic acid, not a ketone. Carboxylic acids contain a carboxyl group (COOH), which consists of a carbonyl group (C=O) bonded to a hydroxyl group (-OH).
This compound is an aldehyde, not a ketone. Aldehydes contain a carbonyl group (C=O) bonded to at least one hydrogen atom and an alkyl or aryl group.
