Ans. Organic compounds can be purified using techniques such as recrystallization, distillation, and chromatography. Recrystallization involves dissolving the compound in a suitable solvent and allowing it to slowly crystallize, resulting in the separation of impurities. Distillation involves heating the mixture to separate the components based on their boiling points. Chromatography involves separating the compounds based on their affinity to a stationary phase and a mobile phase.
