Three compounds A,B and C all have molecular formula `C_(5)H_(8)` All the compound rapidly decolourise `Br_(2)` in `C Cl_(4)`. All three give a position test with Baeyer's reagent. And all the three are soluble in cold conc. `H_(2)SO_(4)`. Compound A gives a precipitate when treated with ammonical `AgNO_(3)` solution. but compounds B and C do not compounds A and B both yield pentane `(C_(5)H_(12))` when they are treated with excess `H_(2)` in the presence of Pt catalyst. Under these conditions, compound C absorbs only one mole of `H_(2)` and gives a product with the formula `C_(5)H_(10)` On oxidation with hot acidified KMnO_4, B gave acetic acid and CH_3CH_2COOH. Identify compounds A, B, and C.
