1)2,2 2)3,2 3)2,3 4)4,3

Answer 1

Answer:

H=

​  

[V+M−C+A]

where,

H= Number of orbitals involved in hybridization.

V=Valence electrons of the central atom.

M- Number of monovalent atoms linked to a central atom.

C= Charge of a cation.

A= Charge of an anion.

Consider the hybridization and shape of the options:-
