Question

use the figures to answer the following question. which molecule shown has a carbonyl functional group in the form of a ketone? a. h h c c h h o h b. h h c c c h h h o h h c. h h c c h h o oh d. h h c n h h h

Explanation:

A ketone has a carbon - oxygen double bond (carbonyl group) where the carbon of the carbonyl is bonded to two other carbon atoms. In molecule B, the carbonyl carbon is bonded to two carbon atoms, making it a ketone. Molecule A has an aldehyde (carbonyl at the end of a chain bonded to a hydrogen), molecule C has a carboxylic acid (carbonyl with an - OH group attached), and molecule D has an amine (nitrogen - containing functional group).

Answer:

B.
