Answer:
Alcohol (D); Amine (B); Carbohydrate (C); Carbonyl group (A).
Step-by-step explanation:
The alcohol function are compounds that have as a functional group hydroxyl (‒OH), linked to saturated carbons, in their structure. They may have unsaturation, cyclic chains and branches. They are usually water soluble and up to eleven carbons are liquids.
Amines are nitrogenous organic compounds theoretically derived from ammonia (NH3) by replacing one, two or three hydrogens with alkyl or aryl groups.
In organic chemistry, carbonyl is a functional group consisting of a carbon and an oxygen atom, bonded by double bond, that enters the composition of aldehydes, ketones, carboxylic acids, esters, halides acids and amides.
Carbohydrates are the most abundant biomolecules in nature, consisting mainly of carbon, hydrogen and oxygen, and may present nitrogen, phosphorus or sulfur in their composition.
