क्रियात्मक समूह

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.
