( C - Cl ) bond in chlorobenzene a comparison to ( C - Cl ) bond in methyl chloride is

Options

  1. Alonger and weaker
  2. Bshorter and weaker
  3. Cshorter and stronger
  4. Dlonger and stronger

Correct answer

C. shorter and stronger

Step-by-step solution

Because of (+R ) effect of Cl-atom with the ring, ( C - Cl ) bond in chlorobenzene gets a double bond character and it becomes shorter and stronger than the ( C - Cl ) bond of in methyl chloride ( ( CH ₃- Cl ) ), which does have such effect.
