Alcohols — practice question

Glycerol is an alcohol molecule containing three -OH groups in each molecule. What equation represents the combustion of glycerol?

  • A$\text{C}_3\text{H}_8\text{O}_3 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}$
  • B$2\text{C}_3\text{H}_8\text{O}_3 + 3\text{O}_2 \rightarrow 6\text{CO}_2 + 8\text{H}_2$
  • C$2\text{C}_3\text{H}_8\text{O}_3 + 7\text{O}_2 \rightarrow 6\text{CO}_2 + 8\text{H}_2\text{O}$
  • D$4\text{C}_3\text{H}_5\text{O}_3 + 11\text{O}_2 \rightarrow 12\text{CO}_2 + 10\text{H}_2\text{O}$
