TRICK TO CALCULATE HYBRIDISATION
Notes on trick to calculate hybridisation of simple molecules
For explanation watch the video on trick to calculate hybridisation 👇
Here you can understand the basic concept of hybridisation with the various examples 👇
Trick to calculate the hybridisation
Hybridization is the process of intermixing of orbitals of slightly different energies so as to redistribute their energies to generate a new set of orbitals of equivalent energies and shape.
Trick to calculate the hybridization of simple molecules
Simple trick that works in calculating the hybridization of simple molecules involving s, p and d orbitals is counting the total number of lone pair and bond pair present in the molecule.
The total number of electron pairs involving in the molecule will determine the type of hybridization.
1. If the total electron pairs (lone pair + bond pair) present in the molecule are 2 then the type of hybridization will be sp and the shape of the molecule will be linear. Some examples of simple molecules showing sp hybridization are C2H2 and BeCl2
2. If the total number of electron pairs (lone pair + bond pair) is equal to 3 then the type of hybridization will be sp2 and the shape of the molecule is trigonal planar some examples of simple molecules showing sp2 hybridisation are BF3 and carbonate ion.
3. If the total number of electron pairs (lone pair + bond pair) is equal to 4 then the type of hybridization will be SP3 and the shape of the molecule is square planar some examples of molecules showing the showing the SP3 hybridization are CH4 and NH4+
Similarly you can calculate the hybridization of more simple molecules involving s p and d orbitals with the same trick as given above in the notes.
