Sigma and Pi Bonds for Quiz 2

[Nasir_Ahmed]

I'm a bit confused. We haven't covered sigma or pi bonds in our lectures or discussion sections. Will they be as prevalent on the Quiz as they are on the practice quizzes?

There won't be any sigma or pi bonds on the quiz. I was told to study for this quiz based on the "Quiz 2 Preparation" quiz that does not have any answers and not look at either of the other two that do have the answers as those may just be more confusing.

Hi,

Does anyone happen to know how to go about solving these problems though? What do the sigma and pi bonds mean in terms of the bonds? Thanks!

Nasir,
In short, when carbon bonds with other atoms, the first bond is always a sigma bond, and any subsequent bond is a pi bond. A single bond between, say, carbon and hydrogen would be on sigma bond. A triple bond between, for example, 2 carbon molecules would be made up of one sigma bond and 2 pi bonds. Sigma and pi bonds actually have to do with the orbitals involved in bonding and how they interact, but this simplified way of looking at it works for solving the quiz 2 prep. Hopefully that helps.
