Which of the following is correct about octane number?
Correct answer: C. Higher the octane number, lower the knocking
- A. Higher the octane number, higher will be knocking
- B. Higher the octane number, efficiency of fuel will be lower
- C. Higher the octane number, lower the knocking
- D. Lower the octane number, lower the knocking
Explanation
The octane number is a measure of a fuel's resistance to knocking. As the octane number increases, the engine is less likely to produce knocking.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
