Which among the following is allylic halide ?

Options

  1. ACH ₃ - CH ₂ - CH ₂ - X
  2. BC ₆ H ₅ CH ₂ - X
  3. CCH ₂ = CH - CH ₂ - X
  4. DCH ₃ - CH = CH - X

Correct answer

C. CH ₂ = CH - CH ₂ - X

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
