  • B. Carbonyl group
  • C. H-atom of OH group
  • D. Carboxyl group

About Carboxylic Acids

Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
