When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is __________ the concentration of the ketone.A) Slightly higher thanB) Equal toC) Much higher thanD) Much lower thanE) Exactly half of

Respuesta :

Answer:

D). Much lower than  

Explanation:

When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is Much lower than the concentration of the ketone

because :

Carbon- oxygen bond is more stable(stronger) than Carbon-Carbon Bond

Keto - enol tautomerism is :

[tex]H -C-C=O \rightleftharpoons C=C-O-H[/tex]

Ketone has C=O and enol has C=C

C=O bond energy is 745 kJ/mol

C=C bond energy is 614 kJ/mol
