How many of the following molecules have two lone pairs of electrons on central atom?

$\mathrm{SF}_6, \mathrm{BF}_3, \mathrm{ClF}_3, \mathrm{PCl}_5, \mathrm{BrF}_5, \mathrm{XeF}_4, \mathrm{H}_2 \mathrm{O}, \mathrm{SF}_4$

The pair of molecules / ions with the same bond order value is

How many of the following molecules / ions have trigonal planar structure?

$$ \mathrm{BO}_3^{3-}, \mathrm{NH}_3, \mathrm{PCl}_3, \mathrm{BCl}_3, \mathrm{ClF}_3, \mathrm{XeO}_3 $$

Consider the following

Assertion (A) Dipole moment of $\mathrm{NF}_3$ is lesser than $\mathrm{NH}_3$.

Reason (R) In $\mathrm{NF}_3$, the orbital dipole due to lone pair of electrons is in the opposite direction to the resultant dipole moment of the three $\mathrm{N}-\mathrm{F}$ bonds.

The correct answer is
