# How many pi-"electrons" in benzene?

Jul 9, 2017

How many double bonds do you see?

#### Explanation:

I see 3 here..........And each such double bond represents $2 \times \pi$ electrons, which are conceived to lie above and below the plane of the benzene ring.......

And since there are 3 bonds, there are $3 \times 2 \pi$ electrons, i.e. $6 \pi$ electrons in total.......

The alternative representation of benzene, an hexagon circumscribing a circle.......

............must be understood to represent those same $6 \times \pi$ electrons.....

How many in this system........?
