I am studying Organic Chemistry. Recently I came up with the formula for finding number of Pure and Hybrid orbital that can be present in a organic compound , That is
Number of Hybrid Orbital = number of "Carbons" * (number denoting the hybridisation of carbon) and
Number of Pure Orbital = number of Hydrogens present + 2* (no of pi orbitals present )
- number of hybrid orbital = 6*(3) = 18 (Hybridisation is sp2 = 1s + 2p = 3)
- number of pure orbital = 6 + 2*3 = 12
which tells that there are 18 hybrid orbital and 12 pure orbital present in Benzene.
My question is , What is the derivation of this formula ? Thanks.
