Ethene to ethanol conditions
WebMedium Solution Verified by Toppr Three steps are involved in the mechanism of hydration of ethene to yield ethanol. (1) The electrophillic attack of hydronium ion protonates ethene to form carbocation. (2) Water (as a nucleophile) attacks carbocation. (3) Deprotonation gives ethanol. The mechanism is shown above.
