Answer:
m-CPBA followed by base catalysed hydrolysis
Explanation:
The scheme of this reaction is shown in the image attached.
We can see here that the acetophenone reacts with metachloroperoxybenzoic acid (m-CPBA) as shown in the image to yield phenyl acetate.
Phenyl acetate is now hydrolysed by a base as shown to yield the acetate ion and phenol.
Answer: 1.79 x 10^-5
Explanation: The equilibrium constant of a reaction can be calculated from the quotient of the concentrations of the products over the concentrations of the reactants, with each termed raised to their respective stoichometric coefficients.
For acetic acid, this equilibrium expression is:
Replacing the equilibrium concentrations given by the exercise into the expression above, the equilibrium constant, Kc will be obtained and it is found to be equal to 1.79 x 10^-5.
