Question

Consider the following molecules: 7 L H,C = ï - CHg Z:-I II III Localised lone pair (on N-atom) is present in
Only III O Only I and III O Only II and III O I, II and III​

Answer 1

Answer:

I don't know

so I will answer later BYE

Answer 2

Localized lone pair is present in I only.

• A lone pair involved in resonance is said to be delocalized.
• Electrons not involved in resonance are called localized.
• In I, the lone pair on N is not involved in resonance since there is complete resonance in the ring among the 3 pi bonds.
• In II and III, we can witness pi bond-lp-pi bond and pi bond-lp-sigma bond resonance respectively.
