Explain the mechanism of dehydration of ethanol

Explanation

Step 1: Formation of protonated alcohol

Step 2: Formation of carbocation
`H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-overset(H)overset(|)(C)-H to H-underset(H)underset(|)overset(H)overset(|)(C)underset(H)underset(|)overset(H)overset(|)(C)+H_(2)O`
Step 3: Formation of ethene by eliminatio of a proton
`H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C^(oplus))-underset(H)underset(|)overset(H)overset(|)(C)=underset(H)underset(|)overset(H)overset(|)(C)+H^(+)`
