For complete combustion, 1 mole of an organic compound requires 8 moles of O2 gas. What could be the formula of the compound?
Correct answer: D. C5H12
- A. C4H8
- B. C4H9OH
- C. C5H11OH
- D. C5H12
Explanation
The formula of the compound with a maximum of 8 moles of oxygen gas required for complete oxidation is C5H12.The combustion reaction for C5H12 is: C5H12 + 8O2 → 5CO2 + 6H2O
