The formation of chemical bond is accompanied by

Options

A. Increase in energy
B. decrease in energy
C. neither decrease nor increase in energy
D. the repulsive forces overcoming the attractive forces

Answer

To solve the question regarding the formation of a chemical bond and its relation to energy, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chemical Bonds**:
- A chemical bond is formed when atoms come together to achieve a more stable configuration. This can involve sharing or transferring electrons.

2. **Stability and Energy Relationship**:
- The stability of a system is related to its potential energy. Generally, systems tend to move towards lower energy states because lower energy states are more stable.

3. **Energy Change During Bond Formation**:
- When a bond is formed, energy is released. This release of energy signifies that the potential energy of the system decreases, leading to increased stability.

4. **Evaluating the Options**:
- **Option A**: Increase in energy - This is incorrect because the formation of a bond leads to a decrease in energy.
- **Option B**: Decrease in energy - This is correct as energy is released when a bond is formed.
- **Option C**: Neither decrease nor increase in energy - This is incorrect since there is a clear change in energy.
- **Option D**: Repulsive forces overcoming attractive forces - This is misleading as attractive forces are what lead to bond formation, not repulsive forces.

5. **Conclusion**:
- The correct answer is **Option B: decrease in energy**. The formation of a chemical bond is accompanied by a decrease in energy, which corresponds to an increase in stability.
