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 $SP^{3}$hybridized while in haloarenes it is $sp^{2}$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.

Answer 1

Answer: (C)

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

Answer 2

The tertiary carbocation formed in the reaction is most stable.
