Question: how many valence electrons are in the phenyl ion c6h5?
Answer: 2 sp2 orbitals form C-C sigma bond, and one p-orbital is used for C-C pi bond. Now the odd electron lies in the 3rd sp2 hybridized orbital, which would have overlapped with the s-orbital of Hydrogen if the molecule were benzene. So, we have just one valence electron.
