Which of the following methods is used to prepare alcohols from alkenes?
Correct answer: C. Reaction of alkene with H2SO4/water
- A. Reaction of alkenes with X2/water
- B. Reaction of alkene with water
- C. Reaction of alkene with H2SO4/water
- D. Reaction of alkene with Ni
Explanation
Option CAlkenes react with water in the presence of concentrated sulphuric acid to form alcoholsCH2=CH2 + H2SO4 ---------> CH3-CH2-O-SO3HCH3-CH2-O-SO3H + H2O -----> CH3-CH2-OH + H2SO4

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
