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

$$ \mathrm{C}_6 \mathrm{H}_5 \mathrm{~N}_2^{+} X^{-} \xrightarrow{\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}} X \xrightarrow[\text { anhy. } \mathrm{AlCl}_3]{\mathrm{CO}, \mathrm{HCl}} Y $$

How many amines with molecular formula $\mathrm{C}_3 \mathrm{H}_9 \mathrm{~N}$ can react with benzenE sulphonyl chloride?

In the following sequence of reactions, what is the end product $(D)$ ?

$$ \mathrm{C}_2 \mathrm{H}_5 \mathrm{Br} \xrightarrow{\mathrm{KCN}} A \xrightarrow{\mathrm{H}_3 \mathrm{O}^{+}} B \xrightarrow{\mathrm{LiAlH}_4} C \xrightarrow[573 \mathrm{~K}]{\mathrm{Cu}} D $$

Consider the following

Statement I : $\mathrm{CH}_3 \mathrm{NH}_2$ is more basic than $\mathrm{NH}_3$ but $\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2$ is less basic than $\mathrm{NH}_3$.

Statement II : The order of basic strength of amines in aqueous phase follows the order $\left(\mathrm{C}_2 \mathrm{H}_5\right)_3 \mathrm{~N}>\left(\mathrm{C}_2 \mathrm{H}_5\right)_2 \mathrm{NH} >\mathrm{C}_2 \mathrm{H}_5 \mathrm{NH}_2$

The correct answer is
