  2. B"r" and "u"
  3. C"p" and "s"
  4. DPredominantly at "u"

Correct answer

D. Predominantly at "u"

Step-by-step solution

The given molecule, benzanilide, contains two phenyl rings with different reactivities towards electrophilic aromatic substitution. The left phenyl ring is attached to the carbonyl carbon of the amide group ( -C(=O)NHPh ). The carbonyl group is electron-withdrawing due to its -M and -I effects, which deactivates this ring towards electrophilic attack. The right phenyl ring is attached to the nitrogen atom of the amide group ( -NHC(=O)Ph ). The nitrogen atom possesses a lone pair of electrons that can delocalize int
