A compound [A] with molecular formula `C_(5)H_(10)O` gave a positive `2,4`-D.N.P. Test but a negtive Tollen's test. It was oxidised to carboxylic acid [B] with molecular formula `C_(3)H_(6)O_(2)` when treated with alkaline `KMnO_(4)` under vigorous conditions. Sodium salt of [B] gave a hydrocarbon [C] on Kolbe's electrolyte reaction. Identify [A],[B] and [C] and write the chemical equations for the reactions.

A compound (X) with a molecualr formula C_(5)H_(10)O gives a positive 2, 4-DNP test but a negative Tollens' test. On oxidation it gives a carboxylic acid (Y) with a molecular formula C_(3)H_(6)O_(2) . Potassium salt of (Y) undergoes Kolbe's reaction and gives a hydrocarbon (Z). (X), (Y) and (Z) respectively are
