The bond having the minimum bond energy is :

Options

A. `C-C`
B. `O-O`
C. `S-S`
D. `P-P`

Explanation

To determine which bond has the minimum bond energy, we need to analyze the factors that influence bond energy. Here’s a step-by-step solution:

### Step 1: Understand Bond Energy
Bond energy is the amount of energy required to break a bond between two atoms. It is influenced by several factors, including the size of the atoms involved, the type of bond (ionic or covalent), and the electronegativity of the atoms.

**Hint:** Remember that larger atoms tend to have lower bond energies due to decreased attraction between their nuclei and bonding electrons.

### Step 2: Analyze Atomic Size and Electronegativity
As we move down a group in the periodic table, the size of the atoms increases due to the addition of electron shells. This increase in size generally leads to lower bond energies because the distance between the nuclei of the bonded atoms increases, resulting in weaker attractions.

**Hint:** Electronegativity increases across a period and decreases down a group, affecting bond strength.

### Step 3: Compare the Atoms in the Question
Consider the atoms mentioned: Carbon (C), Nitrogen (N), Oxygen (O), and Phosphorus (P).

- **Carbon (C)**: Smaller size, higher bond energy.
- **Nitrogen (N)**: Small size, relatively high bond energy.
- **Oxygen (O)**: Smaller size, high electronegativity, high bond energy.
- **Phosphorus (P)**: Larger size, lower bond energy compared to the others.

**Hint:** Focus on the size of the atoms and their position in the periodic table to determine their bond energies.

### Step 4: Determine the Bond with Minimum Energy
Among the atoms analyzed, phosphorus (P) has the largest atomic size. Larger atoms have lower bond energies because the distance between the nuclei is greater, leading to weaker bonds. Therefore, the bond involving phosphorus will have the minimum bond energy.

**Hint:** Larger atomic size generally correlates with lower bond energy due to weaker attractions.

### Conclusion
The bond having the minimum bond energy is the bond involving phosphorus (P).

**Final Answer:** Phosphorus (P) has the bond with the minimum bond energy.
