A hydrocarbon (X) of the formula `C_6H_12` does not react with bromine water but reacts with bromine in presence of light, forming compound (Y).Compound (Y) on treatment with Alc. KOH gives compound (Z) which on ozonolysis gives (T) reduces Tollens reagent which gives compound (W) after acidification . (W) gives iodoform test and after acidification produce compound (U) which when heated with `P_2O_5` forms a cyclic anhydride (V).
Compound V is
