A mixture of three gases A,B and C is passed first into acidified K_(2)Cr_(2)O_(7) solution when A is absorbed turning the solution green. The remainder of the gas is passed through excess of lime water which truns milky resulting in the absorption of B. The residual gas C is absorbed by alkaline pyrogallol solution. However the original mixture does not run lead acetate paper black. Identify A,B, & C ( Give necessary equations ).

7.5 ml of a gaseous hydrocarbon was exploded with 36 ml of O_2 . On cooling the volume of gases was found to be 28.5 ml, 15 ml of which was absorbed by KOH and the rest was absorbed in a solution of alkaline pyrogallol. The formula of hydrocarbon is:

The gas absorbed by oil of turpentine is____.

An unknown gaseous hydrocarbon and oxygen gas are mixed in volume ratio 1:7 respectively and exploded. The resulting mixture upon cooling occupied a volume of V mL , half of which got absorbed in aq. KOH (absorbed CO_(2) ) and the remaining half was absorbed in alkaline pyrogallol solution (absorbs O_(2) ) . Assuming all volumes to be measured under identical conditions :
