Which of the following molecules are diatomic ?
(i) Nitrogen (ii) Neon (iii) Oxygen
(iv) Sulphur (v) Phosphorus (vi) Ozone
(vii) Fluorine (viii) Hydrogen (ix) Fullerene

Options

A. ii,iv,v and vi
B. iv,v and ix
C. ii and vi
D. I,iii,vii and viii

Explanation

To determine which of the given molecules are diatomic, we need to analyze each molecule based on its molecular structure. A diatomic molecule consists of two atoms of the same or different elements.

### Step-by-Step Solution:

1. **Nitrogen (N2)**:
- Nitrogen exists as N2, which means it has two nitrogen atoms bonded together.
- **Conclusion**: Nitrogen is diatomic.

2. **Neon (Ne)**:
- Neon is a noble gas and exists as individual atoms (Ne). It does not form diatomic molecules.
- **Conclusion**: Neon is not diatomic.

3. **Oxygen (O2)**:
- Oxygen exists as O2, indicating it has two oxygen atoms bonded together.
- **Conclusion**: Oxygen is diatomic.

4. **Sulphur (S8)**:
- Sulphur typically exists as S8, which means it consists of eight sulfur atoms in a ring structure.
- **Conclusion**: Sulphur is not diatomic.

5. **Phosphorus (P4)**:
- Phosphorus usually exists as P4, meaning it has four phosphorus atoms in a tetrahedral structure.
- **Conclusion**: Phosphorus is not diatomic.

6. **Ozone (O3)**:
- Ozone is represented as O3, consisting of three oxygen atoms.
- **Conclusion**: Ozone is not diatomic.

7. **Fluorine (F2)**:
- Fluorine exists as F2, indicating it has two fluorine atoms bonded together.
- **Conclusion**: Fluorine is diatomic.

8. **Hydrogen (H2)**:
- Hydrogen exists as H2, which means it has two hydrogen atoms bonded together.
- **Conclusion**: Hydrogen is diatomic.

9. **Fullerene (C60)**:
- Fullerene is a molecule made up of 60 carbon atoms and does not exist as a diatomic molecule.
- **Conclusion**: Fullerene is not diatomic.

### Summary of Diatomic Molecules:
- The diatomic molecules from the list are:
- Nitrogen (N2)
- Oxygen (O2)
- Fluorine (F2)
- Hydrogen (H2)

### Final Answer:
The diatomic molecules are:
- (i) Nitrogen
- (iii) Oxygen
- (vii) Fluorine
- (viii) Hydrogen

**Correct Option**: D (i, iii, vii, viii)
