Draw all resonance contributors for each of the following molecules or ions. Be sure to include the curved arrows that indicate which pairs of electrons are shifted in going from one resonance structure to the next. (a) CH NO, (b) CHCO2 (c) CH,CHCHCH3 (the ion has two C-C single bonds) (d) C.H.N (a ring is formed by the C and N atoms, and each H is bonded to C) (e) C.H.N (a ring is formed by the C and N atoms, the N is bonded to one H, and each C is bonded to one )
