The starting material is a primary alcohol with a 5-carbon chain. First, it undergoes oxidation with PCC to form an aldehyde (2-pentanal). Next, it is treated with methylmagnesium bromide in a Grignard reaction to form a secondary alcohol (2-pentanol). Finally, the secondary alcohol is oxidized with Jones reagent to form a ketone (2-pentanone). Therefore, the major organic product obtained is 2-pentanone.
