Answer

Brief Explanations:

The left column shows the general formula R-X, where X represents a halogen atom (F, Cl, Br, I). This structure corresponds to an alkyl halide functional group. Alkyl halides are commonly used as organic solvents. The right column shows the general formula R-NH₂, which represents an amine functional group (specifically, a primary amine). Amines are known for being weak bases, playing roles in biochemical processes, and often having characteristic foul smells.

Answer:

alkyl halide (left column); amine (right column)
