Which of the following has unstable enol form? - Byju''s
The correct option is D Enol form of (a) is phenol which is an aromatic ring and highly stable. Enol form of (b) is also highly stable because it is aromatic Enol form of (c) is non-aromatic. Enol form of (d) : Here the enol form is highly unstable because it is an anti-aromatic in nature. Hence, keto form of (d) is stable and more dominant.

Which of the following has the highest percentage of enol form in Keto enol …
The correct option is C The enol form of 2, 4-Hexanedione is more stable due to the resonance stability of conjugated double bond and also due to the formation of cyclic six meered ring by hydrogen bonding. Other enol forms of (a), (b) and (d) lack this stabilisation. Hence, (c) has the highest percentage of enol in Keto-enol equilibrium.

Correct order of percentage of enol content is ?\n \n \n \n \n A.$b …
Therefore the correct answer would be B, d > b > c > a. Note: When the keto and the enol form exist, although both are stable, but they constantly interconvert in each other to gain much stability and the correct amount of saturation. Even if one form is more stable doesn’t mean that every molecule converts in it.
