Question

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 $sp^3$ hybridised while in haloarenes it is $sp^2$ hybridised
• 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

Answer 1

Answer: (B)

In haloarenes, carbon of $C—X$ is $sp^2$ hybridised while in haloalkanes it is $sp^3$ hybridised.
