Difference between Bonds

Postby Justin Bui 2L » Sun Dec 03, 2017 11:39 pm

For clarification, there has to be a sigma bond before a pi bond, and there only has to be 1 sigma bond for something like a triple bond, correct? In a triple bond, there is a sigma bond and 2 pi bonds?

Yes there always has to be a sigma bond because every covalent molecule has a sigma bond while not every covalent molecule has a pi bond. Pi bonds are onl;y found in double or triplr bonds.

The first bond made is a sigma bond, any bond after that becomes a pi bond

Sigma is always the first bond and then followed by pi bonds. For example, a triple bond is made up of a sigma bond and 2 pi bonds.

What is an example of how we may be given a test question for sigma and pi bonds?

He'll probably give us a molecule and tell us to draw the lewis structure and label the sigma and pi bonds.

A sigma bond is always first due to the fact that it is lower energy, so if the molecule always picks a lower energy state, it makes sense that a sigma bond is first, it is only after then that any other bond formed are pi because they require more energy then a sigma bond but less energy than the individual atoms, so there is usually 1 sigma bond and n-1 pi bonds with n being total number of bonds
