Give the structures of A, B and C in the following reactions:

(i)\mathrm{CH}_3\mathrm{CH}_2\mathrm{I}\xrightarrow{\mathrm{NaCN}}A\xrightarrow[\text{Partial hydrolysis}]{\mathrm{OH}^-}B\xrightarrow{\mathrm{NaOH}+\mathrm{Br}_2}C

(ii)\mathrm{C}_6\mathrm{H}_5\mathrm{N}_2\mathrm{Cl}\xrightarrow{\mathrm{CuCN}}A\xrightarrow{\mathrm{H}_2\mathrm{O}/\mathrm{H}^+}B\xrightarrow[\Delta]{\mathrm{NH}_3}C

(iii)\mathrm{CH}_3\mathrm{CH}_2\mathrm{Br}\xrightarrow{\mathrm{KCN}}A\xrightarrow{\mathrm{LiAlH}_4}B\xrightarrow[0^{\circ}\mathrm{C}]{\mathrm{HNO}_3}C

(iv)\mathrm{C}_6\mathrm{H}_5\mathrm{NO}_2\xrightarrow{\mathrm{Fe}/\mathrm{HCl}}A\xrightarrow[273\,\mathrm{K}]{\mathrm{NaNO}_2+\mathrm{HCl}}B\xrightarrow[\Delta]{\mathrm{H}_2\mathrm{O}/\mathrm{H}^+}C

(v)\mathrm{CH}_3\mathrm{COOH}\xrightarrow[\Delta]{\mathrm{NH}_3}A\xrightarrow{\mathrm{NaOBr}}B\xrightarrow{\mathrm{NaNO}_3/\mathrm{HCl}}C

(vi)\mathrm{C}_6\mathrm{H}_5\mathrm{NO}_2\xrightarrow{\mathrm{Fe}/\mathrm{HCl}}A\xrightarrow[273\,\mathrm{K}]{\mathrm{HNO}_2}B\xrightarrow{\mathrm{C}_6\mathrm{H}_5\mathrm{OH}}C
