Molecular Orbital Theory (MOT)

The number and type of bonds between two carbon atoms in calcium carbide are

Assertion. Molecular nitrogen is less reactive than molecular oxygen.

Reason. The bond length of ${\mathrm{N}}_2$ is shorter than that of oxygen

Assertion : ${\mathrm{H}}_2$ molecule is more stable than $\mathrm{HeH}$ molecule.

Reason : The anti bonding electron in the molecule destabilises it.
