Reactions of alkenes and alcohols (chemistry only)
Question
- A. As a fuel
- B. As a plasticizer
- C. As a refrigerant
- D. As a pesticide
Answer
The correct option is As a fuel.
Explanation
The correct option is As a fuel. As a fuel is correct because it directly supports the approved learning objective to recall the main uses of these alcohols. This belongs to Alcohols within Reactions of alkenes and alcohols (chemistry only), 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 Alcohol Uses
Students often confuse the uses of different alcohols, thinking they are interchangeable in all applications.
To fix this, students should study the specific properties and uses of each alcohol, such as methanol for industrial solvents, ethanol for beverages, and butanol for fuel.
