Which of the following is the simplest ketone used as an organic solvent?

Lyrx [107]

Answer: Option (d) is the correct answer.

Explanation:

A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.

For example, acetone $CH_{3}-CO-CH_{3}$ is a ketone.

Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula $C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}$ .

A camphor is a volatile white color substance with chemical formula $C_{10}H_{16}O$ . It has aromatic smell and its taste is bitter.

A menthone is also an organic compound with chemical formula $C_{10}H_{18}O$ .

Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.
