An organic compound 'A' on heating with concentrated H_2 SO_4 forms a compound 'B' which on addition of one mole of hydrogen in presence of Ni forms a compound 'C'. One mole of compound 'C' on combustion forms two moles of CO_2 and three moles of H_2 O When 'B' and 'C' are added separately to the test tubes containing orange-brown liquid X', the colour disappears in case of 'B' but remains same in case of 'C'. The name of the liquid X and the substance responsible for colour change are respectively
