alleryThe unique ability of carbon to form strong covalent bonds with other carbon atoms, building large molecules, is called:
ACatenation
BHydrogenation
CPolymerisation
DIsomerism
Answer & Solution
Correct answer: A. Catenation
1. Carbon-carbon covalent bonds are strong and stable.
2. This lets carbon atoms link into long chains and rings, forming very big molecules.
3. This property of self-linking is named catenation.
4. Rule out D: isomerism is having the same molecular formula but different structures, a different cause of variety.
