Web21 jun. 2016 · The three "C"-"H" bonds on each methyl group contribute a total of 6 more sigma bonds. So, we have a total of 18 sigma bonds. Inside the benzene ring, you have delocalized pi electrons over six atoms. The major resonance structure has three pi bonds; one for each double bond. So the result is 18 sigma and 3 pi bonds.
