From: JEE Main 2021 (Online) 17th March Evening Shift
Question
The functional groups that are responsible for the ion-exchange property of cation and anion exchange resins, respectively, are :
Choose an option
Show full solutionCorrect option: A
Correct answer
ASO3H and NH2
Step-by-step explanation
Cation exchange resins contain large organic
a molecule with –SO3H group.
In the cation exchange process H+ exchanges for Na+, Ca2+, Mg2+ and other cations present in water.
While anion exchange resins contain –NH2 in form of –NH3+ OH– where OH– exchanges for anions like Cl–, HCO3–, SO4 2–, etc.
