Show Hint
- \(-\mathrm{SO_3H}\) and \(-\mathrm{NH_2}\)
- \(-\mathrm{NH_2}\) and \(\mathrm{COOH}\)
- \(-\mathrm{NH_2}\) and \(-\mathrm{SO_3H}\)
- \(-\mathrm{SO_3H}\) and \(-\mathrm{COOH}\)
The Correct Option is A
Solution and Explanation
An anion exchange resin exchanges OH- for anions such as Cl- and SO42-; it is a basic resin with amine groups (-NH2 / quaternary ammonium hydroxide).
Answer: (1) -SO3H and -NH2

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
