Concept:
A benzylic halide is a compound in which the halogen atom is attached to a benzylic carbon, i.e., the carbon directly attached to a benzene ring.
Step 1: Understand benzylic position.
\[
\text{C}_6\text{H}_5 - \text{CH}_2 - X \quad (\text{Benzylic halide})
\]
Step 2: Check each option.
(A) Bromophenylmethane â \(\text{C}_6\text{H}_5\text{CH}_2\text{Br}\) â halogen on benzylic carbon \checkmark
(B) 4-Bromotoluene â halogen on ring (aryl halide) $\times$
(C) 1-Bromo-2-phenylethane â halogen not directly on benzylic carbon $\times$
(D) Bromobenzene â halogen directly on benzene ring $\times$
