Benzene $\xrightarrow{HNO_3/H_2SO_4}$ Intermediate $\xrightarrow[Heat]{Sn/HCl}$ Product. Identify the final product.

Predict the major product $P$ in the following sequence of reactions$-$
$(i)$ $HBr$,benzoyl peroxide
(ii) $KCN$
(iii) $Na(Hg)/C_2H_5OH$
[Image: $1-$methylcyclopentene reacting with the above reagents to form $P$]

Explain the ammonolysis of alkyl halide compounds.

What are the products $C$ and $D$ in the given reaction?
$Phthalimide$ $\xrightarrow{KOH} A$ $\xrightarrow{C_2H_5Br} I$ $\xrightarrow{HOH/H^+} C + D$

An organic compound $A$ on treatment with $NH_3$ gives $B$,which on heating gives $C$. $C$ when treated with $Br_2$ in the presence of $KOH$ produces ethyl amine. Compound $A$ is:
