Bromine Substituent

Refers to a bromine atom attached to the carbon skeleton of an organic molecule, affecting its reactivity and properties.

Deactivator

A chemical compound or group that decreases the reactivity of an atom or a formation within a molecule, often used in reference to aromatic substitution reactions.
