Carbon compounds as fuels and feedstock
Question
- A. Increased viscosity of the fuel
- B. Higher energy density per unit volume
- C. Reduced combustion temperature
- D. Lower carbon dioxide emissions
Answer
Higher energy density per unit volume
Explanation
Smaller hydrocarbons have a higher proportion of carbon‑hydrogen bonds per unit volume, giving them a higher energy density, which is desirable for fuels.
Common mistake
Misunderstanding the Demand for Small Molecules
Students often confuse the usefulness of cracked products with the size of the molecules, thinking that all small molecules are fuels.
Clarify that only certain small molecules, specifically those produced from cracking, are in high demand as fuels due to their efficiency and combustion properties.
