Science

Functional groups

In Class 10 Science, this topic from “Carbon and its Compounds” explains how specific atoms or groups of atoms in an organic molecule determine its characteristic properties and reactions. Students learn to identify common functional groups such as hydroxyl, aldehyde, ketone and carboxylic acid groups, represent them in structural formulae, and relate their presence to the naming, properties and chemical behaviour of carbon compounds.

Answer and explanation

Correct answer: A. To remove water and drive the reaction forward

Esterification is a reversible condensation reaction between an alcohol and a carboxylic acid, producing an ester and water. Concentrated sulphuric acid acts mainly as a dehydrating agent, removing or absorbing water and shifting the equilibrium toward ester formation; it also provides acidic catalysis. Therefore option A is correct. The other options describe transformations that do not occur in esterification.
