Drawing OF Resonating Structures and Resonance Hybrid Structure

(a) Write the resonance structures of NO_2^(Ө) (nitrite) and NO_3^(Ө) (nitrate ion) in terms of : (i) outer shell overline e^, s with formal charges (ii) overlapping atomic orbitals. ( c) Compare the resonance (delocalisation) energy adn stabilities of NO_2^(Ө) and NO_3^(Ө) . (b) (i) Write the resonance contributing and hybrid structures of (I) N_2 O (II) H_2 C - N_2 (diazomethane). (ii) Give the hybridised state of each atom in each structure. (iii) Discuss their bond length in each resonance contributing structure and compare with those in hybrid structures.
