Questions asked by users might not always be phrased in the clearest way.
Identify the activators and deactivators from these: -oph, -cho, -nhch3, -chf2, -c(ch3)3
Accepted Answer
Here are the activators and deactivators with explanations:
Activators:
-OPh (Phenoxy group): Activates the ring by donating electron density through resonance. The lone pairs on the oxygen atom can delocalize into the aromatic ring, increasing electron density at the ortho and para positions.
-NHCH3 (N-methylamino group): Activates the ring by donating electron density through resonance and inductive effects. The lone pair on the nitrogen atom can delocalize into the ring, increasing electron density.
Deactivators:
-CHO (Formyl group): Deactivates the ring by withdrawing electron density through resonance and inductive effects. The carbonyl group is electron-withdrawing, decreasing electron density at the ortho and para positions.
-CHF2 (Difluoromethyl group): Deactivates the ring by withdrawing electron density through inductive effects. The fluorine atoms are highly electronegative, making the group electron-withdrawing.
-C(CH3)3 (tert-Butyl group): Deactivates the ring by withdrawing electron density through inductive effects. The alkyl group is electron-donating, but the bulky nature of the tert-butyl group hinders its ability to donate effectively.
