what reaction occurs between 2-methoxy propene and water?

Answer 1

With a little acid present as catalyst, the product is acetone plus methanol. The first product is 2-propenol, but that tautomerizes at once to acetone.

Answer 2

The only real reaction that I see happening is the addition of water on the double bond (at high pressure) to form 2-methoxy-propan-2-ol
