(a) An organic compound ‘A’ with molecular formula C₈H₈O forms an orange red precipitate with 2,4-DNP reagent and gives yellow precipitate on heating with I₂ and NaOH. It neither reduces Tollen’s reagent nor Fehling’s reagent nor does it decolourize bromine water or Baeyer’s reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid ‘W having molecular formula C₇H₆O₂. Identify the compounds ‘A’ and ‘B’ and explain the reactions involved.
(b) Write the mechanism of esterification of carboxylic acids.
