Explanation

To determine which of the given orders of bond strength are correct, we will analyze each option based on the principles of bond strength, which depend on factors such as atomic size and the nature of the bonds involved.

### Step-by-Step Solution:

1. **Option (a): C-C > Cl-Cl > S-S > P-P > O-O**
- **Analysis**:
- Carbon (C) has a small atomic size, leading to a strong bond.
- Chlorine (Cl) is larger than carbon but smaller than sulfur (S) and phosphorus (P), so Cl-Cl bond strength is less than C-C but more than S-S and P-P.
- Oxygen (O) has a high electron density, leading to repulsion between the bonding electrons, making O-O bond weaker than the others.
- **Conclusion**: This order is **correct**.

2. **Option (b): H-H > Ne-N > O-O > F-F**
- **Analysis**:
- H-H bond is strong due to small size.
- Neon (Ne) does not form bonds, making Ne-N invalid.
- O-O is weaker due to electron repulsion, and F-F is also weak for the same reason.
- **Conclusion**: This order is **incorrect**.

3. **Option (c): Cl-Cl > Br-Br > F-F > I-I**
- **Analysis**:
- Cl-Cl bond is stronger than Br-Br due to smaller atomic size.
- F-F bond is weaker due to high electron-electron repulsion.
- I-I bond is the weakest due to large atomic size.
- **Conclusion**: This order is **incorrect**.

4. **Option (d): H-F > H-H > C-C > N-N > O-O**
- **Analysis**:
- H-F has a strong bond due to its ionic character.
- H-H bond is strong due to small size.
- C-C bond is also strong but less than H-H.
- N-N bond is strong due to triple bond formation, stronger than C-C.
- O-O is weak due to electron repulsion.
- **Conclusion**: This order is **incorrect**.

5. **Option (e): 2pπ-2pπ > 2pπ-3pπ > 2pπ-3pπ > 3pπ-3pπ**
- **Analysis**:
- The notation seems to have a printing error, as it repeats terms and lacks clarity.
- **Conclusion**: This order is **incorrect**.

### Final Conclusion:
The only correct order from the options analyzed is **Option (a)**. Therefore, the correct orders of bond strength are:

- **Correct Orders**: A
- **Incorrect Orders**: B, C, D, E
