The correct answer is (C)C4H10.
The ratio of volumes is = 10:40:50 = 1:4:5
All the carbon from the hydrocarbon is in the CO2.
10ml of hydrocarbon produces 40ml of CO2- 1:4 ratio.
So, 1 mole of hydrocarbon has four moles of carbon. All the H ends up in the water.10ml of a hydrocarbon produces 50ml water 1:5 ratio.
Each water molecule has 2 moles of H atoms. So, a 1-mole hydrogen carbon compound has 10 moles of hydrogen, which gives C4H10.
