Question

Reaction of cyclohexene with concentrated sulphuric acid

Answer 1

Sulfuric acid reacted with thecyclohexene because they are unsaturated forming alkyl hydrogen sulfate. The π - electrons of alkenes are very reactive toward sulfuric acid(and other sources of H + ). The π -electrons attack the H + to form a carbocation, which reacts with the bisulfate anion.

Answer 2

Reaction of cyclohexene with concentrated sulphuric acid

• Cyclohexanol is derived from the organic layer that separated after the reaction between cyclohexene and aqueous sulfuric acid solution is complete, and the aqueous sulfuric acid solution is reused frequently.
• Because the carbon atoms in cyclohexane have been saturated with hydrogen, it is not reactive and will not react with strong sulfuric acid. When cyclohexene is present, the solution becomes hazy and heat is emitted. Alkyl hydrogen sulphates will be produced when cyclohexene and concentrated sulfuric acid are combined.
• The interaction of sulphur with carbon results in Sulfur dioxide and water are produced by sulfuric acid. The oxidised and reduced species, also known as the oxidiser or reducer, can be identified by the change in the oxidation state.
• Hydration of alkenes with weak sulfuric acid. Alcohols are produced when any alkene is exposed to diluted sulfuric acid. It's a hydration reaction right now. When a water molecule is added via a double bond, primary, secondary, or tertiary alcohols may result.
