Catenation is the unique property of an element due to which it forms covalent bond with other atoms or the same element. Identify the element.

Options

A. Carbon
B. Hydrogen
C. Neon
D. Aluminium

Answer

To solve the question regarding catenation, we can follow these steps:

### Step 1: Understand the Concept of Catenation
Catenation is defined as the ability of an element to form chains or rings by bonding with itself or with other atoms of the same element. This property is crucial in organic chemistry as it allows for the formation of complex structures.

**Hint:** Remember that catenation involves the self-linking of atoms.

### Step 2: Identify Elements Known for Catenation
Different elements exhibit catenation to varying degrees. The most notable element known for its catenation ability is carbon. Other elements like silicon can also exhibit this property, but to a lesser extent.

**Hint:** Think about which element is the backbone of organic chemistry and is known for forming long chains.

### Step 3: Confirm the Element with the Highest Catenation
Among the elements, carbon is unique due to its ability to form stable covalent bonds with itself, leading to the formation of long chains and complex structures. This property is fundamental to the vast diversity of organic compounds.

**Hint:** Consider which element is most commonly associated with organic compounds and is essential for life.

### Conclusion
The element that exhibits the unique property of catenation, forming covalent bonds with itself and other atoms, is **carbon**.

**Final Answer:** Carbon
