# Show the mechanism of the Pinacol-Pinacolone Rearrangement reaction [duplicate]

In the reactant, due to $$\ce{H+}$$ ion, a positive charge will be created by removing water in place of the rightmost $$-\ce{OH}$$.

But then how will it give such a product. I cant see any way to make the cyclic pentane first.

There would be a Pinacol-Pinacolone Rearrangement but how ?
