Question

match the functional group with its property.
hydroxyl -oh
carbonyl choose
carboxyl choose
amino choose
choose
acidic group - proton donor
-oh
determines the two groups of sugar: aldehydes and ketones

• nh2

Explanation:

Carbonyl Matching:

Carbonyl functional group (C=O) is present in aldehydes (with -CHO) and ketones (with -C=O in the middle of a carbon chain). So its property related to sugars is that it determines the two groups of sugar: aldehydes and ketones.

Carboxyl group is -COOH. The -COOH group can donate a proton (H⁺) to act as an acid, so its property is being an acidic group - proton donor.

Amino functional group is -NH₂, so it should be matched with -NH₂.
