Hybridization and Molecular Geometry of NH3

The video tutorial explains the hybridization of NH3 (ammonia) by examining the regions around the nitrogen atom, including unbonded electron pairs and sigma bonds. It describes how NH3 is SP3 hybridized due to the presence of one s and three p orbitals around the nitrogen atom. The tutorial also covers how hydrogen atoms, with their s orbitals, overlap with these SP3 orbitals. The video concludes with a brief sign-off by Dr. B.
