The reason why a hybrid orbital is better than its parents is as follows: Hybrid orbitals can be defined as the combination of standard atomic orbitals resulting in the formation of new atomic orbitals. Prof. Linus Pauling (1931) first developed the Hybridization state theory in order to explain the structure of molecules such as methane (CH4).1This concept was developed for simple chemical systems but this one applied more widely later on and from todays point of view it is considered an operative empirical for excusing the structures of organic and inorganic compounds along with their related problems.
