Question

Which choice represents a pair of resonance structures? Note that lone pairs have been omitted for clarity. A. N≡C−Br and C≡N−Br B. N≡C− and N≡C−H C. H−H and Br−Br D. N=N=O and N≡N−O

Answer 1

`"Only option D"`

Explanation:

Resonance isomers differ by bond order, not by connectivity or composition.......

For `D.` we gots `""^(-)N=stackrel(+)N=O` versus `N-=stackrel(+)N-O^(-)`; these are both neutral resonance isomers......in which atom connectivity is the same.
