Chemistry Question on Haloalkanes and Haloarenes

For the compounds CH3Cl,CH3Br,CH3ICH_3Cl, \, CH_3Br,\,CH_3I and CH3F,CH_3F, the correct order of increasing CC-halogen bond length is :

A

CH3F<CH3Cl<CH3C<CH3ICH_3F < CH_3Cl < CH_3C < CH_3I

B

CH3F<CH3Br<CH3Cl<CH3ICH_3F < CH_3Br < CH_3Cl < CH_3I

C

CH3F<CH3Cl<CH3Br<CH3ICH_3F < CH_3Cl < CH_3Br < CH_3I

D

CH3Cl<CH3Br<CH3F<CH3ICH_3Cl < CH_3Br < CH_3F < CH_3I

Answer

CH3F<CH3Cl<CH3Br<CH3ICH_3F < CH_3Cl < CH_3Br < CH_3I

Explanation

Solution

As the radius of halogen increases CC?halogen bond length increased.
