Vedclass · Answer

(C) The reaction sequence is an example of Hofmann elimination.$1$. The amine $(CH_3)_2CHCH_2N(CH_2CH_3)_2$ reacts with excess $CH_3I$ to form the quaternary ammonium salt $(CH_3)_2CHCH_2N(CH_2CH_3)_2(CH_3)^+ I^-$.$2$. Treatment with $Ag_2O/H_2O$ converts the iodide salt into the corresponding quaternary ammonium hydroxide $(CH_3)_2CHCH_2N(CH_2CH_3)_2(CH_3)^+ OH^-$.$3$. Upon heating,the Hofmann elimination occurs. The base (hydroxide) abstracts a $\beta$-hydrogen from the ethyl group (which is less sterically hindered than the isobutyl group),leading to the formation of ethene $(H_2C=CH_2)$ and the tertiary amine $(CH_3)_2CHCH_2N(CH_3)CH_2CH_3$.

Assertion $(A)$: $-NH_2$ group of aniline is ortho,para directing in electrophilic substitutions.
Reason $(R)$: $-NH_2$ group stabilises the arenium ion formed by the ortho,para attack of the electrophile.
The correct answer is

In the reaction $CH_3NH_2 + X + KOH \rightarrow CH_3NC + 3KCl + 3H_2O$,what is $X$?

Assertion : Acylation of amines gives a monosubstituted product whereas alkylation of amines gives polysubstituted product.
Reason : Acyl group sterically hinders the approach of further acyl groups.
