An orgnaic acid `P(C_(11)H_(12)O_(2))` can easily be oxidized to a dibasic acid which reacts with ethyleneglycol to product a polymer dacron. Upon ozonolysis, P gives an aliphatic ketone as one of the products. P undergoes the following reaction sequences to furnish R via Q. the compound P also undergoes another set of reactions to produce S.
