Strong Deactivators

Strong Deactivators Definition:

Groups that strongy deactivate an aromatic ring toward electrophilic aromatic substitution, thereby significantly decreasing the rate of the reaction.

Strong Deactivators Explained:

The deactivation depends on a substituent that decreases the rate of a substitution reaction on an aromatic ring. The opposite of activators, they slow down the reaction towards the electrical charges that weaken process.
