In esterification, the OH of carboxylic acid is replaced by:

Correct answer: D. OR

  • A. OR+
  • B. R+
  • C. R
  • D. OR

Explanation

Option D is the correct answer. In esterification, the hydroxyl group (OH) of a carboxylic acid is replaced by an alkyl or aryl group (R) attached to an oxygen atom (O),forming an ester.The general structure of an ester can be represented as RCOOR'. Here, R represents the alkyl or aryl group derived from the carboxylic acid, and R' represents another alkyl or aryl group that can be derived from an alcohol.The formation of an ester involves the condensation reaction between a carboxylic acid and an alcohol, and the elimination of water molecule (H2O).

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.
