The increasing order of reduction of alkyl halides with zinc and dilute HCl is

A

`R-ClltR-IltR-Br`

B

`R-ClltR-BrltR-I`

C

`R-IltR-BrltR-Cl`

D

`R-BrltR-IltR-Cl`

Text Solution

Verified by Experts

The correct Answer is:
B
The reactivity of halogens with alkane is `F_2 gt Cl_2 gt Br_2 gt I_2` . Hence , reduction of alkylhalide with Zn and dilute HCl follows reverse order, i.e.
R-IgtR-BrgtR-Cl. Further, the reactivity of this reduction increases as the strength of C-X bond decreases.
