So for this question, you're asked to find how many pi bonding molecular orbitals benzene has.
00:07
So first, let's think about the lewis structure of benzene, right? a lot of times it's called the benzene ring.
00:21
Where at each corner, there is a carbon, right? so you can just think about carbon at each corner.
00:29
Each carbon also is bonded to a hydrogen.
00:40
And then every other bond is a double bond.
00:44
So a lot of times the single bond of hydrogen is assumed, right? and the corner is just assumed as a carbon.
00:51
So a lot of times you will just see it written like this.
00:58
So in order to find out how many electrons are in pi bonds.
01:08
Remember, a single bond is always a sigma bond, and then pi bonds are present in double bonds or triple bonds.
01:15
So let's look and see how many double bonds we have.
01:21
So we have the one double bond here, another double bond here, and another double bond here...
