Reason : $-NH_2$ group of aniline reacts with $AlCl_3$ (Lewis acid) to give acid-base reaction - 9Given below are two statements : one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.View Solution
Assertion $(A)$ : Experimental reaction of $CH _{3} Cl$ with aniline and anhydrous $AlCl _{3}$ does not give $o$ and $p-methylaniline$.
Reason $(R)$ : The - $NH _{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl _{3}$ and hence yields $m$-methyl aniline as the product.
