$CH_3 - O - \overset{\oplus}{C}H - \overset{\ominus}{C}H - CH = CH_2$

Vedclass · Answer

(C) The stability of resonance structures is determined by several factors: $1$. Structures with more covalent bonds are more stable. $2$. Structures with complete octets for all atoms are more stable. $3$. Structures with negative charge on the more electronegative atom and positive charge on the less electronegative atom are more stable. $4$. Structures with like charges on adjacent atoms are highly unstable due to electrostatic repulsion. In option $C$,we have a structure with adjacent positive and negative charges $(-\overset{\oplus}{C}H - \overset{\ominus}{C}H-)$,which makes it highly unstable compared to the others where charges are separated by double bonds or are on atoms that can accommodate them better.
