Since
(c)
Interpretation: The best method for synthesis of indicated aldehyde from appropriate alcohol should be devised.
Concept introduction:PCC is useful for selective oxidation of primary alcohol to corresponding aldehydes. The tertiary alcohols have no hydrogen so it cannot be oxidized. The structure of pyridinium chlorochromate is as follows:
