The compound shown is treated with PCC in . Which structure is the product?

  1. AStructure A
  2. BStructure B
  3. CStructure C
  4. DStructure D

Answer: A

The compound is hex-5-en-2-ol, a secondary alcohol. PCC oxidises it to the ketone hex-5-en-2-one and leaves the isolated terminal alkene intact. Hydrogenation of the alkene, cleavage of the alkene, or epoxidation are not reactions of PCC.
