Ethyl acetoacetate is a liquid. The value of the tautomeric constant for neat ethyl acetoacetate is Kt = .079. What is the percentage of the enol form in neat ethyl acetoacetate?

To calculate the percentage of the enol form in neat ethyl acetoacetate, we need to use the tautomeric constant (Kt) and the formula:

Enol Percentage = (Kt / (1 + Kt)) * 100.

Given that the tautomeric constant (Kt) for neat ethyl acetoacetate is 0.079, we can substitute this value into the formula:

Enol Percentage = (0.079 / (1 + 0.079)) * 100.

Calculating this expression step by step:

Enol Percentage = (0.079 / 1.079) * 100.

Enol Percentage = 0.073 * 100.

Enol Percentage = 7.3%.

Therefore, the percentage of the enol form in neat ethyl acetoacetate is 7.3%.
