Chloropicrin is manufactured by the reaction between $Cl_2$,$NaOH$ and

$m$-Bromotoluene is prepared by :

Consider the following reaction sequence. The final product $D$ will be:
$C_6H_5CH_3$ $\xrightarrow[\Delta]{KMnO_4/H^+} A$ $\xrightarrow{SOCl_2} B$ $\xrightarrow[\Delta]{NH_3} C$ $\xrightarrow{KOH/Br_2} D$

In the chemical reaction $CH_3Cl$ $\xrightarrow{AgCN} (A)$ $\xrightarrow{H_2/Pd} (B)$,what is the structure of $(B)$?

The electrolytic reduction of nitrobenzene in a strongly acidic medium produces:

Identify $Y$ in the following reaction sequence:
$CH_3-CH(CH_3)-CH_2-CONH_2$ $\xrightarrow{KOBr(aq)} X$ $\xrightarrow{NaNO_2/HCl(aq)} Y$
