Statement I : Sodium hydride can be used as an oxidising agent.
Statement II : The lone pair of electrons on nitrogen in pyridine makes it basic.
Choose the CORRECT answer from the options given below :
Statement II : The lone pair of electrons on nitrogen in pyridine makes it basic.
Choose the CORRECT answer from the options given below :
Show Hint
- Statement I is false but statement II is true
- Both statement I and statement II are true
- Statement I is true but statement II is false
- Both statement I and statement II are false
The Correct Option is A
Solution and Explanation
Statement II: in pyridine the lone pair on nitrogen lies in an sp2 orbital in the plane of the ring and is not part of the aromatic sextet; it is available for protonation, so pyridine is basic. Statement II is true.
Answer: (1) Statement I is false but statement II is true

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:
