Given three reasons for anomalous behaviour of carbon.

Explanation

To answer the question about the anomalous behavior of carbon, we can outline three key reasons that explain why carbon behaves differently compared to other elements in its group (Group 14 of the periodic table).

### Step-by-Step Solution:

1. **High Ionization Energy**:
- Carbon has a significantly higher ionization energy compared to its group counterparts (silicon, germanium, etc.). This means that it requires more energy to remove an electron from a carbon atom than from other group members.
- The high ionization energy is due to its small atomic size and strong effective nuclear charge, which holds the electrons tightly.
