(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How many pi bonds are in the molecule C12H18?

2. Relevant equations

I have in my notes the formula (6nPi+2-total # of electrons)/2.

3. The attempt at a solution

Unfortunately I can't find an explination for this formula in the book and I don't remember what was shown in lecture. I do know that there are 66 valence electrons total in this molecule. I also understand the basic definitions of pi and sigma bonds.
