Question

The ability of an element to form the longest chain with its own atoms is called as

• A. allotropy
• B. hybridization
• C. catenation
• D. isomerism

Answer 1

The Correct Option is C

Correct answer: catenation 

Explanation:
Catenation is the ability of an element to form long chains by bonding with atoms of the same element. This property is especially strong in carbon, allowing it to form long straight, branched, or cyclic chains. It is responsible for the vast number of organic compounds.

- Allotropy refers to the existence of an element in more than one physical form (e.g., diamond and graphite for carbon).
- Hybridization is the mixing of atomic orbitals to form new hybrid orbitals.
- Isomerism refers to compounds with the same molecular formula but different structures.

So, the correct term is catenation.
