In the reaction given below, identify B . CH ₂= CHCl Cl ₂ A [363 ~K ] Ca ( OH )₂ B

Options

  1. A1, 1, 2-trichloroethane
  2. B1, 1-dichloroethene
  3. C1, 2-dichloroethene
  4. Dchloroethylene

Correct answer

B. 1, 1-dichloroethene

Step-by-step solution

The complete reaction is as follows, aligned CH ₂= & CHCl Cl ₂ ClCH ₂- CHCl ₂ & [363 ~K - HCl ] Ca ( OH )₂ 1, dichloroethene (B) CH ₂ = CCl ₂ aligned During dehydrohalogination of (A) , the more acidic hydrogen (i.e. CHCl ₂ ) is eliminated.
