$A 	o S_{N^1} , \, B 	o S_{N^2}$

Vedclass · Answer

(A) The graph shows the variation of reaction rate with the degree of substitution of the alkyl halide.$1$. For $S_{N^2}$ reactions,the rate decreases as the steric hindrance around the reaction center increases. Thus,the rate order is $CH_3-X > Me-CH_2-X > Me_2CH-X > Me_3C-X$. This corresponds to graph $B$.$2$. For $S_{N^1}$ reactions,the rate increases as the stability of the carbocation intermediate increases. Thus,the rate order is $Me_3C-X > Me_2CH-X > Me-CH_2-X > CH_3-X$. This corresponds to graph $A$.Therefore,$A 	o S_{N^1}$ and $B 	o S_{N^2}$.

Which of the following is true about the given graphs $A$ and $B$?
