Consider the following statement (A) NF 3 molecules has a trigonal planar structure. (B) Bond Length of N 2…

In ${\mathrm{NF}}_3$, nitrogen is having three bond pairs and a lone pair, hence, it has pyramidal shape.

The bond order of ${\mathrm{N}}_2=3,$ and The bond order of ${\mathrm{O}}_2=2$. Bond length is inversely related to bond order. Hence, bond length of ${\mathrm{N}}_2$ is shorter than ${\mathrm{O}}_2$

Isoelectronic species have identical bond order

Dipole moment of ${\mathrm{H}}_2\mathrm{O}$ is more than that of ${\mathrm{H}}_2\mathrm{S}$ due to higher electronegativity of $\mathrm{O}$.
