The reaction of methylamine with acetyl chloride is similar to the reaction of aniline with . . . . . . .

Pure aniline is a

In the $Hofmann$ bromamide degradation reaction,the number of moles of $NaOH$ and $Br_2$ used per mole of amine produced are:

Identify the final product $Z$ in the following reaction sequence:
$Aniline$ $\xrightarrow{CH_3COCl} X$ $\xrightarrow{Br_2/AlBr_3} Y$ $\xrightarrow{H_3O^+} Z$

$A$ 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:

What is the product formed when acetamide reacts with $NaOBr$ in an alkaline medium?
