HYBRIDIZATION IN AMMONIA, WATER,ETHYLENE AND ACETYLENE


A short discussion about the hybridization in the remaining  molecules in our syllabus. Hybridization in ethylene and acetylene (not in our syllabus) are posted as video.

Hybridization in Ammonia 


E.C.of ammonia 1s2,2s2,2p3

The four sp3 hybrid orbitals in  ammonia is formed by the overlapping of three half filled orbitals and one filled s- orbital of Nitrogen atom. This is shown in the following diagram.
Geometry of  ammonia is pyramidal

Hybridization in Water

 Electronic configuration of O 1s2,2s2,2p4

The four sp3 hybrid orbitals in  water is formed by the overlapping of two half filled p orbitals. one filled p - orbital and one filled s- orbital of oxygen atom. This is shown in the following diagram.
 Geometry of  water  is V-shaped
