Question

Which of the following compound has more bond enthalpy?

a)CH3I b)CH3F c) CH3Cl d)CH3Br​

Answer 1

$\huge \underline \bold \blue{answer}$

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 CH3F<CH3Cl<CH3Br<CH3I.

Hence, the correct option is (A)

Answer 2

Answer:

OPTION A IS CORRECT

CH31

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
