In electrophilic aromatic substitution reactions the nitro group is ________.

A) a m-director since it destabilizes the meta sigma complex more than the ortho, para
B) a m-director since it destabilizes the meta sigma complex less than the ortho, para
C) an o,p-director since it stabilizes the ortho, para sigma complex more than the meta
D) an o,p-director since it stabilizes the ortho, para sigma complex less than the meta
E) none of the above

Nitro Group

A nitro group is a functional group consisting of a nitrogen atom bonded to two oxygen atoms (−NO2), often contributing to the reactivity of a molecule.

O,p-director

Refers to substituents on an aromatic ring that direct incoming substituents to the ortho and para positions relative to themselves during electrophilic aromatic substitution reactions.

Meta Sigma Complex

A term that is not commonly defined in the field of chemistry, indicating a potential misunderstanding or mislabeling of a concept. NO.
