Question

explain the formation of ch2 with the help of hybridization​

Answer 1

In the formation of CH2=CH2 each carbon atom in its excited state undergoes sp2 hybridisation by intermixing one s- orbital (2s) and two p- orbitals (2p say 2px and 2py) and reshuffling to form three sp2 orbitals. ... That means there exists a sigma bond and a pi bond between two carbon atoms in ethene molecule
