Question 48: The given compound is an example of \_\_\_\_ .
(1) allylic halide
(2) vinylic halide
(3) benzylic halide
(4) aryl halide
Answer: Option (1)
Explanation:
An allylic halide is a compound in which the halogen atom is attached to a carbon atom adjacent to a carbon–carbon double bond.
In the given compound, the halogen atom X is bonded to a carbon atom next to the
\mathrm{C}=\mathrm{C} double bond.
This position is known as the allylic position, not the vinylic position where the halogen would be directly attached to a double bonded carbon.
The halogen is also not directly attached to an aromatic ring,
so it is neither a benzylic halide nor an aryl halide.
Hence, the given compound is an allylic halide,
and the correct option is Option (1).
