Which of the following are not ionic compound/
(i) KCI
(ii) HCI
(iii) `CCI_(4)`
(iv) NaCI

Options

A. (i) and (ii)
B. (ii) and (iii)
C. (iii) and (iv)
D. (i) and (iii)

Explanation

To determine which of the given compounds are not ionic compounds, we need to analyze each compound based on the type of bonding present in them.

### Step-by-Step Solution:

1. **Identify the Compounds**: We have four compounds to analyze:
- (i) KCl
- (ii) HCl
- (iii) CCl₄
- (iv) NaCl

2. **Analyze KCl**:
- KCl (Potassium Chloride) is formed from potassium (K) and chlorine (Cl).
- Potassium donates one electron to chlorine, resulting in the formation of K⁺ and Cl⁻ ions.
- Since there is a transfer of electrons, KCl is an **ionic compound**.

3. **Analyze HCl**:
- HCl (Hydrochloric Acid) consists of hydrogen (H) and chlorine (Cl).
- In HCl, hydrogen and chlorine share electrons to form a covalent bond.
- There is no transfer of electrons, so HCl is a **covalent compound**.

4. **Analyze CCl₄**:
- CCl₄ (Carbon Tetrachloride) is made up of carbon (C) and chlorine (Cl).
- In CCl₄, carbon shares its four valence electrons with four chlorine atoms, forming covalent bonds.
- Since there is sharing of electrons, CCl₄ is also a **covalent compound**.

5. **Analyze NaCl**:
- NaCl (Sodium Chloride) is formed from sodium (Na) and chlorine (Cl).
- Sodium donates one electron to chlorine, resulting in the formation of Na⁺ and Cl⁻ ions.
- As there is a transfer of electrons, NaCl is an **ionic compound**.

6. **Conclusion**:
- From the analysis, we find that:
- KCl is ionic.
- HCl is covalent.
- CCl₄ is covalent.
- NaCl is ionic.
- Therefore, the compounds that are **not ionic** are HCl and CCl₄.

### Final Answer:
The compounds that are not ionic compounds are **(ii) HCl and (iii) CCl₄**. Thus, the correct option is **B (2 and 3)**.
