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

Identify the strongest base from the given compounds.

What are $X$ and $Y$ in the following reaction?

Which one of the following reactions does not occur?

Choose the correct order of basic strength.

Account for the following:
$(i)$ $pK_{b}$ of aniline is more than that of methylamine.
$(ii)$ Ethylamine is soluble in water whereas aniline is not.
$(iii)$ Methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide.
$(iv)$ Although amino group is $o-$ and $p-$ directing in aromatic electrophilic substitution reactions,aniline on nitration gives a substantial amount of $m$-nitroaniline.
$(v)$ Aniline does not undergo Friedel-Crafts reaction.
$(vi)$ Diazonium salts of aromatic amines are more stable than those of aliphatic amines.
$(vii)$ Gabriel phthalimide synthesis is preferred for synthesising primary amines.
