How To Determine Hybridization With Double Bonds. The double and triple bonds found in molecules are actually a combination of bonds. The exponents on the subshells should add up to the number of bonds and lone pairs.
Ethene structure ethene has a double bond between the carbons. 1 bond to another atom or lone pair = s (not really hybridized) 2 bonds to another atom or lone pairs = sp 3 bonds to another atom or lone pairs = sp 2 Total number of bonds including sigma and pi bonds is 4.
