Give the mechanism of preparation of ethoxy ethane from ethanol.

Answer»

SOLUTION :StepI: Protonation of alcohol
`CH_(3)-CH_(2)-underset(..)OVERSET(..)(O)-H+H^(+)overset("slow")(to)CH_(3)-CH_(2)-underset(..)overset(H)overset(|)(""^(+)O)-H`
Step II: Attack of nucleophile:

Step III: Removal of proton
`CH_(3)-underset(H)underset(|)(""^(+)O)-CH_(2)-CH_(3)overset("FAST")(to)CH_(3)-CH_(2)-underset("Ethoxyethane")(O)-CH_(2)-CH_(3)-HI`
