Write the mechanism of the following reaction :
`2CH_(3)CH_(2)Ohoverset("Conc. "H_(2)SO_(4))underset(413 K)rarr CH_(3)CH_(2)-O-CH_(2)-CH_(3)`

Explanation

Mechansim of the reaction can be described in the following steps :
(i) `CH_(3)-CH_(2)-overset(* *)underset(* *)O-H+H^(+)rarr CH_(3)-CH_(2)-underset(* *)overset(* *)(""^(+)O" ")-H`
(ii)
