Which among the following is allylic halide?

Step-by-step solution

An allylic halide is a compound in which the halogen atom is bonded to an sp^3 hybridized carbon atom that is adjacent to a carbon-carbon double bond ( C=C ). In CH ₃ - CH ₂ - CH ₂ - X , the halogen is attached to an sp^3 carbon of an alkane chain, making it an alkyl halide. In C ₆ H ₅ - CH ₂ - X , the halogen is attached to an sp^3 carbon adjacent to a benzene ring, making it a benzylic halide. In CH ₂ = CH - CH ₂ - X , the halogen is attached to an sp^3 hybridized carbon atom which is directly bonded to a carbon-
