Synthesis of Alcohols by Hydration of Alkenes Chemistry Tutorial
- Alkenes are unsaturated hydrocarbons.
- The double bond (C=C) is the active site on the molecule.
- Hydration of alkenes is an addition reaction.
- Water adds across the alkene's double bond in the hydration reaction.
- This addition follows Markovnikov's rule.
(the H+ of H2O goes to the C atom that has the greatest number of H atoms)
- Hydration of alkene reactions are used to produce industrial ethanol from ethene.
- General equation for the hydration of an alkene:
word equation: alkene + water H+
alkanol chemical equation: R- C = C -R' |
+ H-O-H H+
R- C - C -R' |
