Double sigma v. pi bonds

Postby ClaireHW » Thu Nov 16, 2017 10:17 pm

I'm confused about the distinction between a double sigma and a pi bond. Are they the same thing or is there a slight variation?

Thanks!

There is no such thing as a double sigma bond. A double bond consists of one sigma bond and one pi bond. A triple bond consists of one sigma bond and two pi bonds.

So when a there are a sigma and a pi bond, does this mean there are two sigma bonds over lapping?

When there is a sigma and a pi bond that could mean there is a double bound between one atom and another, not that they are overlapping.

I feel like it will be helpful to refer to the p orbitals and their shape/orientation. Each p-orbital are orientated along an axis. In two atoms, with p-orbital bonding, one of the three orbitals will interact head on. The other one/two will be parallel to the other atoms p-orbitals.
