Question

As shown below, electrophilic aromatic substitution on N,N-dimethylaniline is faster than on the unsubstituted aniline.
In other words, the aromatic ring in N,N-dimethylaniline is more activated than the ring is in aniline itself. If the ring is methylated at the 2 and 6 positions, however, then the N,N-dimethyl-substituted compound reacts more slowly in electrophilic aromatic substitution than the unsubstituted compound. Explain both of these results.

Hint: It does not have to do with the number of H atoms on the ring.

NH,
NH,
reacts faster than
but
reacts slower than

Definition Definition Organic compounds with a planar cyclic ring of atoms bonded through alternated single and double bonds. Aromatic organic compounds, also called arenes, are an important class of hydrocarbons under the branch of organic chemistry.
