JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
A gaseous hydrocarbon gives upon combustion \(0.72\, g\) of water and \(3.08\, g\) of \(CO_2.\) The empirical formula of the hydrocarbon is :
- A \(C_2H_4\)
- B \(C_3H_4\)
- C \(C_6H_5\)
- D \(C_7H_8\)
Answer & Solution
Correct Answer
(D) \(C_7H_8\)
Step-by-step Solution
Detailed explanation
\(18 \mathrm{g} \mathrm{H}_{2} \mathrm{O}\) contain \(2 \mathrm{g} \mathrm{H}\) \(\therefore 0.72 \mathrm{g} \mathrm{H}_{2} \mathrm{O}\) contain \(0.08 \mathrm{g} \mathrm{H}\) \(44 \mathrm{g} \mathrm{CO}_{2}\) contain \(12 \mathrm{g} \mathrm{C}\)…
