Which of the following molecule has triple bond ?

Options

A. `O_(2)`
B. `N_(2)`
C. `P_(4)`
D. `S_(8)`

Answer

To determine which molecule has a triple bond, we will analyze the bonding in each of the given molecules step by step.

### Step 1: Understand the Concept of Bonds
Bonds are formed when atoms share or transfer electrons. The types of bonds include single bonds (one pair of shared electrons), double bonds (two pairs of shared electrons), and triple bonds (three pairs of shared electrons).

### Step 2: Analyze the Given Molecules
We will analyze the bonding in the following molecules: O2, N2, P4, and Acetate.

1. **Oxygen (O2)**
- Oxygen has an atomic number of 8, with an electronic configuration of 1s² 2s² 2p⁴.
- Each oxygen atom has 6 valence electrons.
- To complete their octet, each oxygen shares 2 electrons, forming a double bond.
- **Conclusion**: O2 has a double bond, not a triple bond.

2. **Nitrogen (N2)**
- Nitrogen has an atomic number of 7, with an electronic configuration of 1s² 2s² 2p³.
- Each nitrogen atom has 5 valence electrons.
- To complete their octet, each nitrogen shares 3 electrons, forming a triple bond.
- **Conclusion**: N2 has a triple bond.

3. **Phosphorus (P4)**
- Phosphorus has an atomic number of 15, with an electronic configuration of 1s² 2s² 2p⁶ 3s² 3p³.
- In P4, each phosphorus atom forms three single covalent bonds with other phosphorus atoms.
- **Conclusion**: P4 has single bonds, not triple bonds.

4. **Acetate (C2H3O2)**
- In the acetate ion, the carbon atoms are bonded to each other and to oxygen atoms through single and double bonds.
- The structure does not involve any triple bonds.
- **Conclusion**: Acetate does not have a triple bond.

### Final Conclusion
From the analysis, we can conclude that the molecule that has a triple bond is **N2** (Nitrogen gas).
