Carbon compounds as fuels and feedstock
Question
- A. They are used only for heating
- B. They are used to produce fuels and chemicals
- C. They are only used in plastics
- D. They are not used in modern life
Answer
The correct option is They are used to produce fuels and chemicals.
Explanation
The correct option is They are used to produce fuels and chemicals. They are used to produce fuels and chemicals is correct because it directly supports the approved learning objective to give examples to illustrate the usefulness of cracking and explain how modern life depends on the uses of hydrocarbons. This belongs to Cracking and alkenes within Carbon compounds as fuels and feedstock, so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
Common mistake
Misunderstanding the Importance of Cracking
Students often fail to connect the process of cracking with its significance in providing smaller, more useful hydrocarbons for fuels and chemicals.
To fix this, students should focus on examples of how cracking produces valuable products like alkenes and fuels, and understand the high demand for these smaller molecules in modern applications.
