A carbon compound ‘P’ on heating with excess conc.  H2 SO4  forms another carbon compound ‘Q’ which on  addition of hydrogen in the presence of nickel catalyst  forms a saturated carbon compound ‘R’. One molecule  of ‘R’ on combustion forms two molecules of carbon  dioxide and three molecules of water. Identify P, Q  and R and write chemical equations for the reactions  involved.
