Haloalkanes And Haloarenes Question 13
Question 13 - 2024 (31 Jan Shift 2)
The correct order of reactivity in electrophilic substitution reaction of the following compounds is :
(1) $B>C>A>D$
(2) $D>C>B>A$
(3) $A>B>C>D$
(4) $B>A>C>D$
Show Answer
Answer (4)
Solution
Formula: Electrophilic Substitution Reaction
$-CH _3$ shows $+M$ and $+I$.
$-Cl$ shows $+M$ and $-I$ but inductive effect dominates.
$-NO _2$ shows $-M$ and $-I$.
Electrophilic substitution $\alpha \frac{1}{-M \text { and -I }}$
$\alpha+M$ and $+I$
Hence, order is $B>A>C>D$.
