How to check hybridisation states of carbon atom in a compound ?
(1)To determine the types of hybridisation formed in carbon is to determine the number of atoms or groups that are attached to the carbon atom If the number is:
(i) 2 then sp
(ii)3 then sp2
(iii)4 then sp3
(2) The formula to calculate hybridization is :
n =1/2 [group no. central atom + no. of monovalent atoms attached to central metal atom + magnitude of negative charge - magnitude of positive charge]
If n=2 hybridisation is sp
n=3 hybridisation is sp2
n=4 hybridisation is sp3
n=5 hybridisation is sp3d etc.
