Answer 1

Concepts and reason

The concept used to solve this question is dehydration of alcohol.

Protonation of the alcohol forms a good leaving group followed by the rearrangement of carbocation and then removal of proton forms the double bond in the product.

Fundamentals

The curved arrow shows the movement of the electron pair. Curved arrow is represented as:

The tail of the arrow begins at an electron pair and the head represents that moving of an electron pair.

The mechanism is as follows:

The mechanism is as follows:

The mechanism is as follows:

The mechanism is as follows:

Ans:

The mechanism with the curved arrow representation is as follows:
