In ethene (ethylene) 'C' involved in SP2 hybridization and forms one sigma bond with another SP2 hybridised carbon and forms two Sigma bonds with two hydrogen atoms.
so in ethylene there is a double bond between one carbon atom and other carbon atom out of these two bonds one bond is sigma bond formed by the SP2 hybridised orbitals and another bond is pi bond formed by the P orbitals of two carbon atoms.
in acetylene the carbon atom undergoes SP hybridization in between the two carbon atoms 1 sigma bond is formed by the overlapping of to SP hybridized orbitals .2 Pi bonds which are formed by the overlapping of pure atomic p orbitals.

what is double covalent bond
double bond formed between two atoms
yes know it but i want to say that give the full explanation
As per valence bond theory a double bond is formed between any two atoms because of overlapping of atomic orbitals or hybridized orbitals. if there are two bonds between any atoms one bond is definitely a sigma bond which is exclusively formed by axial overlapping of atomic orbitals or overlapping of hybridized orbitals and other Bond definitely should be π bond which should be formed by lateral overlapping of only pure atomic orbitals.
what do you think about this explanation do you think is it correct or do you think it is wrong
