Question

The correct order of boiling point for the following methyl halides is

A. CH3I> CH3Br> CH3Cl> CH3F B. CH3I< CH3Br< CH3Cl< CH3F

C. CH3F> CH3Br> CH3Cl> CH3I D. none of the above​

Answer 1

Answer:

option b is correct hope you understood

Answer 2

Answer:

C-halogen bond length totally depends on the electronegativity difference between Carbon and halogen. The more the difference is, the less is the bond length. The electronegativity order of halogens is I<Br<Cl<F. Hence, the correct order of increasing C-halogen bond length is CH

3

F<CH

3

Cl<CH

3

Br<CH

3

I.

Hence, the correct option is (A)
