JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
On complete combustion, \(0.492\,g\) of an organic compound gave \(0.792\,g\) of \(CO _2\).The \(\%\) of carbon in the organic compound is \(..................\) (Nearest integer)
- A \(42\)
- B \(43\)
- C \(48\)
- D \(44\)
Answer & Solution
Correct Answer
(D) \(44\)
Step-by-step Solution
Detailed explanation
weight of \(C\) in \(0.792\,gm CO _2\) \(=\frac{12}{44} \times 0.792=0.216\) \(\% \text { of } C \text { in compound }=\frac{0.216}{0.492} \times 100\) \(=43.90 \%\) Ans:\(44\)
