Step-by-Step Solution

(a) Compounds containing a methyl ketone group (R−CO−CH3R-CO-CH_3) undergo the Haloform reaction when treated with sodium hypohalite (NaOXNaOX). (b) Benzene reacts with COCO and HClHCl in the presence of anhydrous AlCl3AlCl_3 or CuClCuCl to form benzaldehyde. This is known as the Gattermann-Koch reaction. (c) Carboxylic acids having an lpha-hydrogen (R−CH2−COOHR-CH_2-COOH) undergo halogenation at the lpha-position when treated with Cl2Cl_2 or Br2Br_2 in the presence of red phosphorus to give lpha-halocarboxylic acids. This is the Hell-Volhard-Zelinsky (HVZ) reaction. (d) Carboxylic acids (R−COOHR-COOH) react with alcohols (R′OHR'OH) in the presence of an acid catalyst to form esters. This process is called Esterification.
