alleryWhich property of carbon allows it to form long chains?
ATetravalency only
BCatenation
CHigh atomic mass
DIonic character
Answer & Solution
Correct answer: B. Catenation
1. Catenation is the self-linking property of an element.
2. Carbon-to-carbon bonds are short and strong, allowing long chains.
3. Tetravalency alone does not explain chain formation.
4. So catenation is the key property.
