Connected reactions

• Dehydration: Cyclohexanol → Cyclohexene

  Cyclohexanol gives cyclohexene through dehydration.

• Secondary alcohol oxidation: Cyclohexanol → Cyclohexanone

  Oxidation removes hydrogen from the O-H group and its attached carbon, creating a C=O bond. Because that carbon already bonds to two other carbons, the product is a ketone and the six-membered ring is retained.

• Ketone reduction: Cyclohexanone → Cyclohexanol

  Hydride adds to the planar carbonyl carbon while the pi electrons move onto oxygen. Subsequent protonation gives cyclohexanol; the existing carbon ring remains intact.
