Is Benzcne same as 1,3,5-Cyclohexatriene ?

In 1,3,5-Cyclohexatriene, there are three >C=C< (double bond ) having bond length 134 pm and three C-C (single bond) having bond length 154 pm, whereas in benzene all the six C-C bonds have same bond length 139 pm. Due to that fact 1,3,5-Cyclohexatriene give addition reaction while benzene does not. Thus benzene is not same as  1, 3,5-cyclohexatriene.

Nitrobenzene and not benzene, is used as a solvent for Fricdel Craft alkylation of bromobenzene. Why ?

Bromo substituted benzene is preferentially more reactive than Nitro substituted benzene hence it would preferentially undergo alkylation if il is used as a solvent.On the other hand, in nitrobenzene is so strongly deactivating that nitrobenzene does not undergo Friedel Craft reaction.

How does it account for benzene's extraordinary stability ? Give an orbiial picture of benzene ?

The ring is comprised of six sp2 hybridized carbon's each sigma bonded  to carbon’s and an H. (Fig-1) Each Carbon  also has a "p" AO with one electron :  the AO's project above and below the plane of the ring which is a nodal plane. Rather than form three localized alternating doubic bonds (cycIohexatriene). these "p" AO's overlap  laterally to form an extended π-system in which the electrons  are symmetrically delocalized over all six carbon's making the Carbon's equivalent . (Fig-2) Delocalization results in less electron repulsion, greater stabilizalion, and lower energy.
