The elements of VA group direcly combines with halogens and form trihalides of the type `MX_(3) (M-VA` group element, X- halogen). All the trihalides are stable except `NCl_(3),NBr_(3)` and `NI_(3)`.
The tetrahedral structure with a particular hybridisation of the central atom of `NX_(3) (X =F, CI,Br,I)`

Options

A. possesses pyramidal shape with a lone pair of electrons on their central atom with `sp^(3)` hybridisation
B. possesses tetrahedral shape without lone pair of electrons on their central atom with `sp^(3)` hybridiation
C. possesses angular shape without lone pair of electrons on their central atom with `sp^(3)` hybridisation
D. possesses angular shape without lone pair of electrons on their central atom with `sp^(3)d` hybridisation.

Answer

A

Explanation

`NF_(3)` to `NI_(3):`Lewis basic nature increases
