Chapter 4.7, Problem 4.61P
Interpretation Introduction
Interpretation:
The positions that are prone to electrophilic
Concept Introduction:
Deactivators are electron withdrawing groups attached to the benzenes that have either positive charge or an atom with high electronegativity. They are meta directors.
- Strong deactivators: They are very strong electron withdrawing groups.
- Moderate deactivators: It contains a pi bond that is attached to a strong electronegative group.
- Weak deactivators: It consists of halogens.
Activators are electron donating groups attached to the benzenes that have either electron density that is able to push into benzene ring or a lone pair of electrons. They are ortho-para directing.
- Strong activators: It contains a lone pair next to the aromatic ring.
- Moderate activators: It has a lone pair next to the aromatic ring that can take part in the resonance outside the ring as well.
- Weak activators: It consists of alkyl groups.
Halogens are deactivators that are ortho-para directing.

A
Note that the first reactant is used in excess, that is, there is much more of the first reactant than the second.
If there won't be any products, just check the box under the drawing area instead.
