Which of the following hydrocarbons is least reactive?
Correct answer: B. Alkane
- A. Alkyne
- B. Alkane
- C. Benzene
- D. Alkene
Explanation
Alkanes are saturated hydrocarbons containing only strong, non-polar carbon-carbon and carbon-hydrogen single bonds (sigma bonds). The absence of weaker pi bonds or functional groups makes them relatively inert and the least reactive class of hydrocarbons.

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.
