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 \(12 \mathrm{g} \mathrm{C}\)…
