A gaseous hydrocarbon gives upon combustion `0.72 g` of water and `3.08` f of `CO_(2)`. The empirical formula of hydrocarbon isA. `C_(2)H_(4)`B. `C_(3)H_(4)`C. `C_(6)H_(5)`D. `C_(7)H_(8)` |

Answer» Correct Answer - D `18g H_(2)O` contains `2g H` `:. 0.72 g H_(2)O` contains `0.08 g H` `44 g CO_(2)` contains `12 g C` `:. 3.08 g CO_(2)` contains `0.84 g C` `:. C : H = (0.84)/(12): (0.08)/(1) = 0.07:00.08 = 7 : 8` `:. ` Empirical formula `= C_(7)H_(8)`. |
