Question

Define hybridization and explain structure of NH3 and SF4 on the basis of hybridization

Answer 1

hybridisation is the concept of mixing two pure atomic orbitals to form the hybrid orbitals.
NH3
see the valence electrons;
N =5and H=1

hence structure is
..
H -- N -- H
|
H

SF4
valence electrons;
S=6and F=7

..
F -- S -- F
|. |
F F


hope it helps
for any query DM me
if u found it useful plz.mark it brainliest

Answer 2

Hi, my friend....
Here is your answer.

Hybridization is the process of intermixing of atomic orbitals of different energies and then redistribute the energies to make the new orbital which have identical shape....

Structure of NH3 is the example of SP3 hybridisation. Its geometry is pyramidal or tetrahedral due to the presence of lone pair which creates so much replusion.
