Parts and what they mean

• Acetanilide with the lone pair on N (N पर एकाकी युग्म वाला ऐसीटैनिलाइड) — Curved arrows: the N lone pair forms an N=C π bond while the C=O π electrons move onto oxygen.
• Dipolar resonance structure (N⁺=C–O⁻) (द्विध्रुवी अनुनादी संरचना (N⁺=C–O⁻)) — Shows that the N lone pair is partly held by the acetyl group.
• Effect on the ring (वलय पर प्रभाव) — The lone pair is less available for donation to the benzene ring, so –NHCOCH₃ is a weaker activator than –NH₂ (but still o/p-directing).
