Convert Benzene $\rightarrow 3$-Bromophenol by choosing appropriate reagents [(i) to (v)] in the correct sequence.

(i) $\mathrm{NaNO}_2 / \mathrm{HCl}\left(0^{\circ} \mathrm{C}\right)$

(ii) Conc. $\mathrm{HNO}_3 / \mathrm{H}_2 \mathrm{SO}_4$

(iii) $\mathrm{H}_2 \mathrm{O} / 283 \mathrm{~K}$

(iv) $\mathrm{Fe} / \mathrm{HCl}$

(v) $\mathrm{Br} 2 / \mathrm{Fe}$

What is the final product $[\mathrm{Z}]$ formed when the given reactions take place?

Benzene diazonium chloride when warmed with water gives a compound, whose Sodium salt when reacted with Allyl bromide gives compound $[\mathrm{X}]$. Identify $[\mathrm{X}]$.
