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: D

The compound is pentan-1-ol. PCC in anhydrous stops the oxidation of a primary alcohol at the aldehyde, giving pentanal. The acid would need aqueous Cr(VI) such as Jones reagent, and a primary alcohol cannot give a ketone.
