Acid Catalysed Hydration of Alkenes
Explanation:
- When alkenes undergo acid-catalysed hydration, they react with water in the presence of an acid catalyst such as sulfuric acid to form alcohols.
- The hydration of alkenes typically follows Markovnikov's rule, where the hydrogen atom adds to the carbon atom with more hydrogen atoms attached, and the hydroxyl group adds to the carbon atom with fewer hydrogen atoms attached.
- Alkenes other than ethene lead to the formation of secondary or tertiary alcohols.
Reasoning:
- In the acid-catalysed hydration of alkenes, the mechanism involves the formation of a carbocation intermediate.
- The stability of the carbocation intermediate plays a crucial role in determining the product formed.
- Alkenes other than ethene have alkyl groups attached to the double bond, which stabilizes the carbocation intermediate due to hyperconjugation and inductive effects.
- This stabilization allows for the formation of secondary or tertiary alcohols depending on the specific alkene substrate.
Conclusion:
- Therefore, in the acid-catalysed hydration of alkenes except ethene, the formation of secondary or tertiary alcohols is favored due to the stability of the carbocation intermediate.
