Both $\mathrm{BF}_3$ and $\mathrm{NF}_3$ are covalent compound. $\mathrm{BF}_3$ is non polar compound but $\mathrm{NF}_3$ is polar. The reason is :
1 Boron is a solid and nitrogen is a gas in free state
2 Boron is a metalloid while nitrogen is non metal
3 $\mathrm{BF}_3$ is planar but $\mathrm{NF}_3$ is pyramidal in shape
4 Atomic size of boron is smaller than that of nitrogen

Assertion: $\mathrm{F}_2$ and $\mathrm{O}_2{ }^{2-}$ have bond order 1 while $\mathrm{N}_2, \mathrm{CO}$ and $\mathrm{NO}^{+}$have bond order 3 . Reason: Higher the bond order, higher is the stability of the molecule.
1 If both Assertion and reason are true and Reason is the correct explanation of Assertion.
2 If both Assertion and reason are true but Reason is not the correct explanation of Assertion.
3 If Assertion is true but Reason is false.
4 If both Assertion and Reason are false.
Explanation:
Isoelectronic molecules and ions have identical bond orders. $\mathrm{F}_2$ and $\mathrm{O}_2{ }^{2-}$ are isoelectronic with 18 electrons each and $\mathrm{N}_2, \mathrm{CO}$ and $\mathrm{NO}^{+}$are isoelectronic with 14 electrons each.
