An organic compound having \(\mathrm{C}, \mathrm{H}\) and \(\mathrm{O}\) has \(13.13 \% \mathrm{H}, 52.14 \% \mathrm{C}\) and \(34.73 \%\) O. Its molar mass is \(46.068 \mathrm{~g}\). What are its empirical and molecular formulae?
- A \(\mathrm{C}_2 \mathrm{H}_6 \mathrm{O}, \mathrm{C}_4 \mathrm{H}_{12} \mathrm{O}_2\)
- B \(\mathrm{CH}_3 \mathrm{O}, \mathrm{C}_2 \mathrm{H}_6 \mathrm{O}_2\)
- C \(\mathrm{C}_2 \mathrm{H}_6 \mathrm{O}, \mathrm{C}_2 \mathrm{H}_6 \mathrm{O}\)
- D \(\mathrm{C}_2 \mathrm{H}_6 \mathrm{O}_2, \mathrm{C}_3 \mathrm{H}_9 \mathrm{O}_4\)
Answer & Solution
Correct Answer
(C) \(\mathrm{C}_2 \mathrm{H}_6 \mathrm{O}, \mathrm{C}_2 \mathrm{H}_6 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
\[\begin{aligned}& \therefore \text { Empinical formula }=\mathrm{C}_2 \mathrm{H}_6 \mathrm{O} \\& \begin{aligned}\text { Empirical formula mass } & =2(12)+6(1)+1(16) \\& =46\end{aligned}\end{aligned}\] Molecular mass \(=46\)…
