Which one of the following is most reactive towards nucleophilic substitution reaction?

Options

  1. ACH ₂= CH - Cl
  2. BC ₆ H ₅ Cl
  3. CCH ₃ CH = CH - Cl
  4. DClCH ₂- CH = CH ₂

Correct answer

D. ClCH ₂- CH = CH ₂

Step-by-step solution

Stability of corresponding carbocation CH ₂= CH - + C H ₂ CH ₂= + C H C ₆ H ₅⁺ So, ClCH ₂- CH = CH ₂ is most reactive towards nucleophilic substitution reaction.
