Why is the C—Cl bond length shorter in haloarenes compared to haloalkanes?

Options

  1. ADue to a greater s-character of carbon in haloarenes
  2. BDue to a greater s-character of chlorine in haloarenes
  3. CDue to a lower s-character of carbon in haloarenes
  4. DDue to a lower s-character of chlorine in haloarenes

Correct answer

A. Due to a greater s-character of carbon in haloarenes

Step-by-step solution

The C—Cl bond length is shorter in haloarenes because sp2 hybridized carbon in haloarenes has greater s-character.
