MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Allylic halides are compounds in which the halogen atom is bonded to an sp^3 hybridized carbon atom adjacent to a carbon-carbon double bond (C=C). In CH _2 = CH - CH _2 - X , the halogen atom X is attached to the sp^3 hybridized carbon atom which is directly attached to the C=C double bond. Thus, it is an allylic halide. CH _3 - CH _2 - CH _2 - X is a primary alkyl halide. C _6 H _5 CH _2 - X is a benzylic halide. CH _3 - CH = CH - X is a vinylic halide. Answer: CH _2 = CH - CH _2 - X
