Moderate Deactivators

Moderate Deactivators Definition:

Groups that moderately deactivate an aromatic ring toward an electrophilic aromatic substitution

Moderate Deactivators Explained:

deactivators have a positive charge on the substituent or a very electronegative atom attached to it, which “pulls” electrons out of the benzene. All activators and halogens are ortho-para directors; Deactivators (not halogens) are meta-directing. Being Moderate means it’s electrical charge is a bit less electronegative making it mildly attracted to other electrons.
