Concept:A benzylic halide has a halogen atom bonded to a
sp3 carbon atom that is directly attached to a benzene ring.
Explanation:Identify the position of the halogen in each compound.
Bromobenzene: Bromine is directly on the ring, so it is an aryl halide.
Bromophenylmethane: Its structure is
C6​H5​CH2​Br, where bromine is on the carbon directly attached to the ring, making it a benzylic halide.
4-Bromotoluene: Bromine is on the ring, so it is an aryl halide.
1-Bromo-2-phenylethane: Its structure is
C6​H5​CH2​CH2​Br, where bromine is on the second carbon, not the benzylic carbon.
Thus, the halogen must be present on the benzylic carbon.
Answer:B. Bromophenyl methane
