Double Bonds

Postby Adrienne Johnson 1D » Sat Oct 29, 2016 12:51 pm

If you have a double bond, will there always be a sigma bond and a pi bond? Or are there there cases where there are more or less of those bonds?

No, a double bond will always have only one sigma and one pi bond; there will never be more or less for a double bond.

This is due to the overlap of orbitals. Single bonds such as C-C is an overlap of the sp3 orbitals, and is just one sigma bond. As the bonds get stronger (double = sigma + pi, triple = sigma + 2pi) the bond length gets shorter, representing the overlap of further orbitals as well as the heightened strength of the bonds.
