Question

At 300 K and 1 atmospheric pressure, 10 m L of a hydrocarbon required 55 m L of O 2 for complete combustion, and 40 m L of C O 2 is formed. The formula of the hydrocarbon is:, C 4 H 8, C 4 H 10, C 4 H 6, C 4 H 7 C l

Let hydrocarbon is C x H y 10 x = 40 ; x = 4 and 10 x + y 4 = 55 x + y 4 = 55 10 x + y 4 = 5.5 Put the value of x 4 + y 4 = 5.5 y 4 = 5 . 5 - 4 y 4 = 1 . 5 then y = 6 Hence hydrocarbon is C 4 H 6
