Give three reasons for anomalous behaviour of carbon.

Explanation

To answer the question regarding the anomalous behavior of carbon, we can outline three key reasons as follows:

### Step-by-Step Solution:

1. **Small Size**:
- Carbon has the smallest atomic radius among the group 14 elements (which include silicon, germanium, tin, and lead). This small size leads to a higher effective nuclear charge, resulting in stronger bonds. The strong carbon-carbon bond is a result of this small size, which enhances catenation (the ability of an element to form chains with itself).

2. **High Electronegativity**:
...
