Question

The Lewis structures (A) to (F) of species with the formula C H 2 ​ N 2 ​ are given below. Which pair represents two resonance contributors of the same molecule ?

TestHub · Accepted Answer

Resonance contributors differ only in the position of electrons. C (HN=C=NH) becomes F ( H N − − C ≡ N H + ) by shifting one π pair onto N. A and C, A and E, B and D have different atom connectivity or different hydrogen positions, so they are isomers.
