Why is the circled and arrowed answer right for number 6,8,9,10
In electrophilic aromatic substitution reactions, a phenyl substituent on the aromatic ring is _____ A) a deactivator and a m-director B) a deactivator and ano, p-director C) an activator and a m-director D) an activator and an o, p-director E) none of the above Which of the following is an intermediate in the bromination of toluene? In electrophilic aromatic substitution reactions the nitro group is _____ A) am-director since it destabilizes the meta sigma complex more than the ortho, para B) am-director since it destabilizes the meta sigma complex less than the ortho, para C) ano, p-director since it stabilizes the ortho, para sigma complex more than the meta D) ano, p-director since it stabilizes the ortho, para sigma complex less than the meta E) none of the above Which of the following compounds will react least rapidly when treated with CH_3CH_2Cl and AlCl_3?
