Which of the following relation is/are correct?

Options

A. Covalent character `prop` Pseudo inert configuration
B. Ionic character `prop` Inert configuration
C. Covalent character `prop (1)/("Dipole moment")`
D. Ionic character `prop (1)/("Dipole moment")`

Explanation

To determine which of the following relations are correct, we will analyze each statement step by step.

### Step 1: Analyze the first statement
**Statement:** Covalent character is proportional to pseudo inert configuration.

- **Explanation:** Pseudo inert gas configuration refers to the electron configuration of elements that resemble noble gases but have one or two electrons less in their outer shell. These configurations lead to increased effective nuclear charge (Z_eff), which enhances the covalent character of bonds. Therefore, this statement is **true**.

### Step 2: Analyze the second statement
**Statement:** Ionic character is directly proportional to inert configuration.

- **Explanation:** An inert gas configuration is associated with stable ions. When an atom achieves an inert gas configuration, it typically means that it has lost or gained electrons to form a stable ion. The stability of these ions correlates with their ionic character. Thus, this statement is also **true**.

### Step 3: Analyze the third statement
**Statement:** Covalent character is inversely proportional to dipole moment.

- **Explanation:** The dipole moment is a measure of the separation of positive and negative charges in a bond. A higher covalent character in a bond usually leads to a lower dipole moment because the bond is more covalent and less ionic. Therefore, if covalent character increases, the dipole moment decreases, which means this statement is **true**. However, it is important to note that if covalent character is inversely proportional to dipole moment, it implies that ionic character would be directly proportional to dipole moment, which is not true. Thus, this statement is **true**.

### Conclusion
Based on the analysis:
- Statement A: True
- Statement B: True
- Statement C: True

Therefore, all the statements (A, B, and C) are correct.

### Final Answer:
The correct options for the question are A, B, and C.
