Count the total number of σ bonds and π bonds in the compound below:

Hey guys. So, in this problem it's our job to figure out how many different sigma bonds we have and how many PI bonds we have, okay?. Remember, that a sigma bond is an S orbital overlap, right? And a PI bond is a p orbital overlap you need to have an S orbital overlap, a sigma bond, before you can get your PI bond, okay? So you can imagine it like your S orbital overlap, right? Your Sigma bond is your bridge and then your p orbital overlap, your PI bond is going to be your extra support or something, okay? So guys, let's take a look and I'm going to go ahead and highlight in blue our Sigma bonds, okay? So let's see we have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, okay? But guys I also missed some, right? We have one here and another one here, right? So, how many do we have in total? Guys we have 16 in total, okay? So, here we go, the total number is 16, okay? But now the green is going to equal PI bonds, okay? So, how many of those do we have? Well, those are double and triple bonds, right? We have one PI bond for our double bond, okay? And we have two for our triple bond here and here, right? So guys we have a total number of 3 PI bonds, okay guys? So, just remember that when you have a triple bond it's two pi bonds, a double bond is one PI bond and for each of those you still have one Sigma bond. Alright guys, let's move on to the next question, let me know if you have any other questions.
