The resonance effect is defined as 'the polarity produced in the molecule by the interaction of two pi-bonds or between a pi-bond and lone pair of electrons present on an adjacentatom.' The effect is transmitted through the chain. In positive resonance effect, the transfer of electrons is away from an atom or substituent group attached to the conjugated system. This electron displacement makes certain positions in the molecule of high electron densities. In negative resonance effect, the transfer of electrons is towards the atom or substituent group attached to the conjugated system. The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha carbon, is

1.	The resonance effect is defined as 'the polarity produced in the molecule by the interaction of two pi-bonds or between a pi-bond and lone pair of electrons present on an adjacentatom.' The effect is transmitted through the chain. In positive resonance effect, the transfer of electrons is away from an atom or substituent group attached to the conjugated system. This electron displacement makes certain positions in the molecule of high electron densities. In negative resonance effect, the transfer of electrons is towards the atom or substituent group attached to the conjugated system. The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha carbon, is
Answer» a CARBONYL COMPOUND with a hydrogen atom on its alpha-carbon RAPIDLY EQUILIBRATES with its corresponding enol and this process is KNOWN as carbonylation a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as keto-enol tautomerism a carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol a carbonyl compound with a hydrogen atom on its alpha-carbon radidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration. Solution :is the correct answer.
