(B) (B) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
Solution & Explanation
\textbf{Answer:} (B) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i) \textbf{Solution:} (a) Benzene with over anhydrous / gives benzaldehyde, the Gattermann-Koch reaction (ii). (b) A methyl ketone with gives carboxylate plus haloform , the Haloform reaction (iii). (c) Alcohol plus carboxylic acid with conc. gives an ester, Esterification (iv). (d) A carboxylic acid with /red P then water gives the alpha-halo acid, the Hell-Volhard-Zelinsky reaction (i).
