10 ml of gaseous hydrocarbon on combustion gives 20 ml of co2 and 30ml of h2o. the hydrocarbon is?

Answers (1)

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 hydrocarbon produces 50ml water 1:5 ratio,

Each water molecule has 2 moles of H atoms. So, 1 mole hydrogen carbon compound has 10 moles of hydrogen. Which gives C4​H10​.
