Sigma vs Pi Bonds

Postby Madeleine Farrington 1B » Sun Jun 10, 2018 7:30 pm

Are all bonds involving the p-orbital Pi bonds? If not, how do you tell if a bond is a Pi bond or a Sigma bond?

I think it has to do more with the number of bonds. So a single bond is a sigma bond, a double is a sigma and pi bond, and a triple is one sigma and two pi bonds.

Is this all we have to know in regards to stating what bonds there are?

I believe so, but we might also be tested on the composition of each bond for ex. σ (H 1s, C 2sp^2) would be the composition of a C-H bond

. Yes the number of bonds are important but more the reasoning behind why these bonds are done like this as when visualizing the different orbitals that the electrons overlap in show that when there are more than 1 bonds, the bond immediately goes to a pi bond as the bonds are side by side because the only end to end bond has already been created. Sigma bonds overlap end to end while pi bonds overlap side to side.
