प्रश्न
Resonance structures of propenal are given below. Which of these resonating structures is more stable? Give reason for your answer.
\[\ce{\underset{I}{CH2 = CH - CH = O} <-> \underset{II}{\overset{⊕}{C}H2 - CH = CH - \overset{Θ}{O}}}\]
उत्तर
The structure I will be more stable than structure II because all the atoms are having complete octet in structure I and the carbon atom having positive charge don’t have a complete octet in structure II.
