The increasing order of reduction of alkyl halides with zinc and dilute HCl is.
A
R-Cl<R-I<R-Br
B
R-Cl < R-Br < R-I
C
R-I < R-Br <R – Cl
D
R-Br < R-I < R-Cl
Answer
R-Cl < R-Br < R-I
Explanation
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.
