Answer:

How many double bonds do you see?

Explanation:

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

And since there are 3 bonds, there are #3xx2pi# electrons, i.e. #6pi# electrons in total.......

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

chemistry.stackexchange.com

............must be understood to represent those same #6xxpi# electrons.....

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