3,3-Dimethylbutan-2-of loses a molecule of water in the presence of a concentrated sulphuric acid to give tetramethyl ethylene as a major product. Suggest a suitable mechanism.

Explanation

`CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-underset(OH)underset(|)(CH)-CH_(3)underset(Delta)overset("Conc."H_(2)SO_(4))rarrunderset("(major product)")(CH_(3)-overset(CH_(3))overset(|)C=overset(CH_(3))overset(|)C-CH_(3))+H_(2)O`
Mechanism of above reaction is represented as follows:
