The main difference in C - X bond of a haloalkane and a haloarene is

A) C - X bond in haloalkanes is shorter than haloarenes

B) in haloalkanes the C attached to halogen in C - X bond is \[s{{p}^{3}}\] hybridised while in haloarenes it is \[s{{p}^{2}}\] hybridized

C) C-X bond in haloarenes acquires a double bond character due to higher electronegativity of X than haloalkanes

D) haloalkanes are less reactive than haloarenes due to difficulty in C-X cleavage in haloalkanes.

Correct Answer: B

Solution :

In haloarenes, carbon of C-X is \[s{{p}^{2}}\]hybridised while in haloalkanes it is \[s{{p}^{3}}\]hybridised.
