How do you count sigma and pi bonds?
Can you give me an example?
Sure! Let's take ethylene, C2H4, as an example. It has one sigma bond between the two carbon atoms, and four sigma bonds between the carbons and the hydrogens. It also has one pi bond between the carbon atoms. So the total number of sigma bonds is 5 (1 between the carbons and 4 between the carbons and hydrogens), and the total number of pi bonds is 1.
