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

Which statements are True? $A$. In Hoffmann bromamide degradation, $4$ moles of $NaOH$ and $1$ mole of $Br_{2}$ are consumed per mole of an amide. $B$. Hoffmann bromamide reaction is not given by alkyl amides. $C$. Primary amines can be synthesized by Hoffmann bromamide degradation. $D$. Secondary amide on reaction with $Br_{2}$ and $NaOH$ will give secondary amine. $E$. The by-products of Hoffmann degradation are $Na_{2}CO_{3}$, $NaBr$ and $H_{2}O$. Choose the correct answer from the options given below:

Compound $A$ is converted to $B$ on reaction with $CHCl_3$ and $KOH$. The compound $B$ is toxic and can be decomposed by $C$. $A, B$ and $C$ respectively are:

$A$ student has been given a compound $x$ of molecular formula $C_6H_7N$. $x$ is sparingly soluble in water. However, on addition of dilute mineral acid, $x$ becomes soluble in water. $x$ when treated with $CHCl_3$ and $KOH$ (alc.) produces $y$. $y$ has a specific unpleasant smell. On treatment with benzenesulphonyl chloride, $x$ gives a compound $z$ which is soluble in alkali. The number of different $H$ atoms present in $z$ is:

Identify $B$ formed in the reaction: $Cl-(CH_2)_4-Cl$ $\xrightarrow{\text{excess } NH_3} A$ $\xrightarrow{NaOH} B + H_2O + NaCl$
