Which from following is obtained by hydroboration - oxidation of propene?

Options

  1. APropanal
  2. BPropanone
  3. CPropan-1-ol
  4. DPropan-2-ol

Correct answer

C. Propan-1-ol

Step-by-step solution

Hydroboration-oxidation of an alkene results in the anti-Markovnikov addition of water across the double bond. Propene ( CH₃-CH=CH₂ ) reacts with diborane ( B₂H₆ ) to form tripropylborane as an intermediate. Subsequent oxidation with hydrogen peroxide ( H₂O₂ ) in an alkaline medium yields propan-1-ol. CH₃-CH=CH₂ [2. H₂O₂, OH^-] 1. B₂H₆ CH₃-CH₂-CH₂-OH Answer: Propan-1-ol
