What are $X$ and $Y$ respectively in the following set of reactions?

Accomplish the following conversions:
$(i)$ Nitrobenzene to benzoic acid
$(ii)$ Benzene to $m-$bromophenol
$(iii)$ Benzoic acid to aniline
$(iv)$ Aniline to $2,4,6-$tribromofluorobenzene
$(v)$ Benzyl chloride to $2-$phenylethanamine
$(vi)$ Chlorobenzene to $p-$chloroaniline
$(vii)$ Aniline to $p-$bromoaniline
$(viii)$ Benzamide to toluene
$(ix)$ Aniline to benzyl alcohol.

$9.3 \ g$ of pure aniline upon diazotisation followed by coupling with phenol gives an orange dye. The mass of orange dye produced (assume $100\%$ yield/conversion) is . . . . . $g$. (nearest integer)

Product $D$ is:-

In a reaction of aniline,a coloured product $C$ was obtained as shown below:
$A$ $\xrightarrow{NaNO_2/HCl} B$ $\xrightarrow{N,N-dimethylaniline, \text{cold}} C$
The structure of $C$ would be:

The relative rate of reaction of the following amines with methyl iodide is:
