Vedclass · Answer

(A) The stability of resonance structures is determined by the following rules:$1$. 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 more electronegative atoms and positive charge on less electronegative atoms are more stable.Structure $I$ $(CH_2=CH-CH=O)$ has all atoms with complete octets and no formal charges,making it the most stable.Structure $II$ $(^+CH_2-CH=CH-O^-)$ has a positive charge on carbon and a negative charge on oxygen,which is relatively stable due to electronegativity,but it has fewer covalent bonds than $I$.Structure $III$ $(-CH_2-CH=CH-O^+)$ has a negative charge on carbon and a positive charge on oxygen,which is highly unstable due to the positive charge on the highly electronegative oxygen atom.Therefore,the decreasing order of stability is $I > II > III$.

Arrange the following in the decreasing order of stability:
$I. CH_2=CH-CHO$
$II. ^+CH_2-CH=CH-O^-$
$III. ^-CH_2-CH=CH-O^+$
