JEE Main · 2021 · 16 Mar 2021 · Shift 2 · Hydrogen

In sodium hydride the hydrogen is at the oxidation state $-1$ and the hydride ion is a powerful electron donor, so sodium hydride acts as a strong reducing agent and a strong base and never as an oxidising agent. In pyridine the nitrogen is $s{p}^2$ hybridised and its lone pair sits in an $s{p}^2$ orbital lying in the ring plane, outside the aromatic sextet, so the pair stays available to a proton and the molecule is basic. Statement I is false and Statement II is true.
