Q.
The increasing order of reduction of alkyl halides with zinc and dilute $HCl$ is
Hydrocarbons
Solution:
The increasing order of reduction of alkyl halides with zinc and dil. $HCl$ is
$R— Cl < R— Br < R— I$
As the size of the halogen increases down the group, the strength of $C — X$ bond decreases, as a result, reactivity increases.
