Vedclass · Answer

(C) The stability of resonance structures is determined by the following rules:$1.$ Atoms with complete octets are more stable.$2.$ $A$ greater number of covalent bonds increases stability.$3.$ Negative charges are more stable on more electronegative atoms ($O$ vs $C$).In structure $(c)$,$CH_2=N^+(O^-)-O^-$,all atoms (including $C$,$N$,and $O$) have complete octets,and the negative charges are placed on the highly electronegative oxygen atoms. This makes it the most stable and significant contributing structure.
