What is a sp2 and sp3 hybridized bond?

They are hybridizations involving 3 and 4 sigma bonds, respectfully.


An sp2 hybridization is when an atom (say, carbon in #C_2H_4#) has 3 sigma bonds, since pi bonds don't hybridize. Carbon's sigma bonds are the two C-H bonds and the 1 C-C bond in its double bond with carbon.

An sp3 hybridization follows the same concept, except there are four sigma bonds instead of 3, like carbon's hybridization in #CH_4#.
