Which of the following is the correct order regarding the electronegativity of hybrid orbitals of carbon?

In an octahedral structure, the pair of d-orbitals involved in ${\mathrm{d}}^2{\mathrm{sp}}^3$ hybridisation is

Assertion. ${\mathrm{BF}}_3$ molecule is planar but ${\mathrm{NF}}_3$ is pyramidal.

Reason. $\mathrm{N}$ atom is smaller than $\mathrm{B}$

Assertion. ${\mathrm{SeCl}}_4$ does not have a tetrahedral structure.

Reason. $\mathrm{Se}$ in ${\mathrm{SeCl}}_4$ has two lone pairs

Assertion. ${{\mathrm{NO}}_3}^{-}$ is planar while ${\mathrm{NH}}_3$ is pyramidal.

Reason. $\mathrm{N}$ in ${{\mathrm{NO}}_3}^{-}$ has ${\mathrm{sp}}^2$ and in ${\mathrm{NH}}_3$ has ${\mathrm{sp}}^3$ hybridization.

Statement-I. ${\mathrm{BF}}_3$ molecule is planar while ${\mathrm{NF}}_3$ is pyramidal.

Statement-2. $\mathrm{N}$ atom is smaller than $\mathrm{B}$.
