Question

Using curved arrows, show the mechanism of the following reaction:

Short answer

Using curved arrows, we will show the mechanism of the following reaction:

Step-by-step solution

How the reaction proceed

1. Oxygen lone pair attacks on hydrogen then hydrogen bond shifts towards oxygen to release water and carbocation will form.

2. Then oxygen of water attacks on carbon and double bond of carbon and oxygen shifts on oxygen and oxygen completes its electrons.

3. Now oxygen gets positive charge and by the attack of another water molecule it takes hydrogen from compound and make it stable and form hydronium ion.

4. Hence the desired product formed.

Final answer

Hence the mechanism is-
