Ncert Exercises & Solutions

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

1. $R - Cl < R - I < R - Br$

2. $R - Cl < R - Br < R - I$

3. $R - I < R - Br < R - Cl$

4. $R - Br < R - I < R - Cl$

HINT: Weaker bond of halogen with carbon gets easily reduced.

EXPLANATION (2).
The reactivity of halogens with alkane is $F_{2} > {Cl}_{2} > {Br}_{2} > I_{2}$ . Hence, reduction of alkyl halide with Zn and dilute HCl follows reverse order i.e., $R - I > R - Br > R - Cl$ . Further, the reactivity of this reduction increases as the strength of C-X bond decreases.
