What is the product formed when a primary amine reacts with a ketone?

Which of the following amines, when heated with ethanolic $KOH$ and chloroform $(CHCl_3)$, does $NOT$ produce a foul smell?

Isomeric amines with molecular formula $C_8H_{11}N$ give the following tests:
Isomer $(P) \Rightarrow$ Can be prepared by Gabriel phthalimide synthesis.
Isomer $(Q) \Rightarrow$ Reacts with Hinsberg's reagent to give a solid insoluble in $NaOH$.
Isomer $(R) \Rightarrow$ Reacts with $HONO$ followed by $\beta$-naphthol in $NaOH$ to give a red dye.
Isomers $(P), (Q)$ and $(R)$ respectively are:

Identify $X$ in the reaction:
$p$-chloroaniline $\xrightarrow[\text{heat}]{CHCl_3/KOH}$ Intermediate $\xrightarrow[300 \ K]{HCl}$ $X$

If $279 \ g$ of aniline is reacted with one equivalent of benzenediazonium chloride,the maximum amount of aniline yellow formed will be $.........$ $g$. (nearest integer)
(consider complete conversion)

Product $(B)$ in this reaction is
