In esterification, the OH group of carboxylic acid departs as?
Correct answer: D. H2O
- A. OH-
- B. OH+
- C. H3O+
- D. H2O
Explanation
In esterification, the hydroxyl group (OH) of the carboxylic acid departs as a water molecule (H2O). This process occurs during the reaction between a carboxylic acid and an alcohol, resulting in the formation of an ester and water as a byproduct. Here's the general equation for the esterification reaction: R-COOH + R'-OH → R-COOR' + 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.
