$CH_3NH_2 + CHCl_3 + KOH \rightarrow$ Nitrogen containing compound $+ KCl + H_2O$. The nitrogen-containing compound is:

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
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 $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.

Complete the following acid-base reactions and name the products:
$(i)$ $CH_{3}CH_{2}CH_{2}NH_{2} + HCl \rightarrow$
$(ii)$ $(C_{2}H_{5})_{3}N + HCl \rightarrow$

In the series of reactions: $C_6H_5NH_2$ $\xrightarrow{NaNO_2/HCl}_{0 - 5\ ^\circ C} X$ $\xrightarrow{HNO_2}_{H_2O} Y + N_2 + HCl$. $X$ and $Y$ are respectively:
