Vedclass · Answer

(A) The stability of resonating structures is determined by the following rules:$1$. Neutral structures are more stable than charged structures. Structure $I$ is neutral,while $II$ and $III$ are charged. Thus,$I$ is the most stable.$2$. Between charged structures,the structure with the negative charge on the more electronegative atom (Oxygen) and the positive charge on the less electronegative atom (Carbon) is more stable. In structure $II$,the negative charge is on the oxygen atom,whereas in structure $III$,the positive charge is on the oxygen atom.$3$. Therefore,the stability order is $I > II > III$.

The order of relative stability of the contributing structures is:
$I: CH_2=CH-CHO$
$II: ^+CH_2-CH=CH-O^-$
$III: ^-CH_2-CH=CH-O^+$
