Chemistry · Organic chemistry – some basic principles and techniques

In the direct quantitative estimation of oxygen, the organic compound is pyrolyzed over red-hot coke at 1373 K and subsequently reacted with \( \text{I}_2\text{O}_5 \): \( 2\text{C} + \text{O}_2 \xrightarrow{1373\text{ K}} 2\text{CO} \) \( \text{I}_2\text{O}_5 + 5\text{CO} \rightarrow \text{I}_2 + 5\text{CO}_2 \) How many moles of \( \text{CO}_2 \) are produced for each mole of \( \text{O}_2 \) liberated from the organic compound?

1. A
   1 mole of \( \text{CO}_2 \)
2. B
   2 moles of \( \text{CO}_2 \)
3. C
   5 moles of \( \text{CO}_2 \)
4. D
   2.5 moles of \( \text{CO}_2 \)
