Mark the correct increasing order of reactivity of the following compounds with HBr/HCl.
| (a) |  |
| (b) |  |
| (c) |  |
पर्याय
a < b < c
b < a < c
b < c < a
c < b < a

उत्तर
b < c < a
Explanation:
It is type of nucleophilic substitution reaction followed by SN1 mechanism. SN1 mechanism depends on the stability of carbonation. Presence of electron-withdrawing group will decrease the stability of carbocation.
