alleryWhich unique property of carbon, by which it links with other carbon atoms to form long chains, allows it to form millions of compounds?
ASublimation
BIonisation
CCatenation
DCrystallisation
Answer & Solution
Correct answer: C. Catenation
1. The huge number of carbon compounds arises from carbon bonding to itself.
2. The property of an element joining with its own atoms to form chains is called catenation.
3. Carbon shows catenation strongly, so it forms long chains and rings.
4. Therefore the answer is catenation.
