Re: Sigma Vs Pi

I think the main thing you need to recognize is when they occur so sigma would be a single bond, a double would be both a sigma and pi bond, and a triple bond would be two pi bonds and one sigma bond.

Re: Final tips

I know it's fairly late for this advice now but I think that one of the best ways to study would have been by doing as many homework problems as possible from the many sections, reading the text book, and looking over the past tests that we have been given!
