Question

The number of Sigma bonds in o xylene is

Answer 1

Hi there,

All hexagons have six sides, contributing 6 σ bonds.

Each C − H bond on the benzene ring adds one σ bond, for a total of 4.

The C − C bond with each methyl group counts as one σ bond, contributing a total of 2 σ bonds.

The three C − H bonds on each methyl group contribute a total of 6 more σ bonds.

So, we have a total of 18 σ bonds.

Along with 3$\pi$.
