A trinitro compound, $1, 3,5$ tris-($4$-nitrophenyl) benzene, on complete reaction with an excess of $\mathrm{Sn} / \mathrm{HCl}$ gives major product, which on treatment with an excess of $NaNO_2 / HCl$ at $0^{\circ} C$ provides $P$ as the product. $P$, upon treatment with excess of $H_2 O$ at room temperature, gives the product $Q$. Bromination of $Q$ in aqueous medium furnishes the product $R$. The compound $P$ upon treatment with an excess of phenol under basic conditions gives the product $S$.
