Re: types of bonds
A single bond would have 1 sigma bond, a double bond would have a sigma bond and a pi bond, and a triple bond would have a sigma bond and 2 bonds.

Re: Pi and Sigma Bonds
The way that it works is that a single bond would have a sigma bond. A double bond would have a sigma bong and pi bond and a triple bond would have a sigma bond and two pi bonds.
