Question

22. 50 ml of a gaseous hydrocarbon is mixed with excess of oxygen and burnt and cooled to the laboratory temperature. The reduction in vol- ume was found to be 150 ml. The gas is then passed into caustic potash, when there is a further reduction in the volume of 150 mL. Provided all the volumes are measured at the same condi- tions of temperature and pressure, find out the molecular formula of the hydrocarbon.​

Answer 1

$\sf \pink{ \tt{Answer}} : -$

The reduction in volume was found to be 150 mL. The gas is then passed into caustic potash, when there is a further reduction in the volume of 150 mL. Provide all the volumes are measured at the same conditions of temperature and pressure, find out the molecular formula of the hydrocarbon.

$∴ \sf \red{ \tt{{y}^{2} (50) = 150}} \\ \implies \: \sf\green{\tt{y = 6}}$

Answer 2

The reduction in volume was found to be 150 mL. The gas is then passed into caustic potash, when there is a further reduction in the volume of 150 mL. Provide all the volumes are measured at the same conditions of temperature and pressure, find out the molecular formula of the hydrocarbon.
