What type of difference is observed in hybridization of carbon of benz

1.	What type of difference is observed in hybridization of carbon of benzene during nitration and formaiton of 6 complex ?
Answer» SOLUTION :Intermediate `SIGMA`-complex is formed in which one carbon POSSESS `sp^(3)` hybridization and rest all carbon possess `sp^(2)` hybridization.
