An organic compound contains 78% (by wt.) carbon and remaining percentage of hydrogen. The right option for the empirical formula of this compound is: [Atomic wt. Of C is 12, H is 1]

Solution & Step-by-step Explanation

Percentage of Carbon = 78% Percentage of Hydrogen = 100 - 78 = 22% Step 1: Calculate relative moles:Moles of C = \frac{78}{12} = 6.5 Moles of H = \frac{22}{1} = 22 Step 2: Find the simplest molar ratio:Ratio of C = \frac{6.5}{6.5} = 1 Ratio of H = \frac{22}{6.5} \approx 3.38 \approx 3 Empirical formula is CH_{3} .
