The order of stability of benzyl carbocations is: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/7e789344515d90e089a32b026c8c6798-.jpeg" /> The electron withdrawing effect of-NO2 group is greater than that of -Cl group. Thus, the correct increasing order of reactivity with HBr/HCl is: (ii) < (iii) < (i).

Q. Mark the correct increasing order of reactivity of the following compounds with $H B r / H Cl$ .

$(i) < (ii) < (iii)$

$(ii) < (i) < (iii)$

$(ii) < (iii) < (i)$

$(iii) < (ii) < (i)$

The order of stability of benzyl carbocations is :

The electron withdrawing effect of- $N O_{2}$ group is greater than that of $- Cl$ group.
Thus, the correct increasing order of reactivity with $H B r / H Cl$ is : $(ii) < (iii) < (i)$ .
