Analyze Statement I: "Sodium hydride can be used as an oxidising agent."

Sodium hydride is $\text{NaH}$, which contains the hydride ion $\text{H}^-$. The hydride ion is a strong reducing agent, not an oxidising agent, because it readily donates electron density / hydride to other species.

For example, $\text{NaH}$ is commonly used as a strong base and reducing species in reactions.

Therefore, Statement I is false.

Analyze Statement II: "The lone pair of electrons on nitrogen in pyridine makes it basic."

In pyridine, the nitrogen atom is $sp^2$ hybridised. One lone pair is present on nitrogen in an $sp^2$ orbital, and this lone pair is not involved in the aromatic sextet.

Since this lone pair is available for donation to a proton, pyridine behaves as a base.

Therefore, Statement II is true.

Choose the correct option:

• Statement I: False
• Statement II: True

Hence, the correct option is A: Statement I is false but statement II is true.

Comparison with stored answer:

Stored correct answer = A

My derived answer = A

So, they agree.
