C - C l bond is stronger than C – I bond, because

Options

  1. AC - C l bond is more ionic than C – I
  2. BC - C l bond is polar covalent bond
  3. CC - C l bond is more covalent than C – I
  4. DC - C l bond length is longer than C – I

Correct answer

A. C - C l bond is more ionic than C – I

Step-by-step solution

C - Cl bond is more ionic than C - I bond because of the greater difference in electronegativities of C and Cl as compared to that of carbon and iodine. Therefore, C - Cl bond is stronger than C - I bond.
