7.5 ml of a gaseous hydrocarbon was exploded with 36 ml of oxygen. The volume of gases on cooling 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.

Heya User,

Here's your answer
______________________

Solution:

15 ml is CO2
=> [ 15/7.5 = 2 atoms of C per molecule ]

13.5 ml is O2 

So, 22.5 ml of O2 was used
=> [ 7.5 ml goes into water, so 7.5 ml of H2 ]

Hence, the gas is Ethyne is “C2H2”.

{ Sorry, but I am not sure about my given answer }
