CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES
317687
Assertion : Enol form of cyclohexane \(-1,3,5\) - trione is more stable than its keto form. Reason : Enol form contains \(\alpha\)-hydrogen atoms.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Enol form of cyclohexane -1,3,5-trione i.e., phloroglucinol. It is stabilized by resonance and possesses aromatic character. Enol forms contains \(\alpha-\mathrm{H}\) atoms. Hence more stable. But it has no relation with given assertion. So, the option (2) is correct.
