Options

A. Greater thanx
B. Less than x
C. Equal to x
D. None of these

Explanation

To solve the question regarding the bond lengths of the C-C bond in ethylene (C₂H₄) in isolated conditions and in Zeise's salt, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bond Length in Isolated C₂H₄:**
- In isolated conditions, the C-C bond length of ethylene (C₂H₄) is given as \( x \).

2. **Understand the Structure of Zeise's Salt:**
- Zeise's salt is represented as \([PtCl_3(C_2H_4)]^-\). In this complex, ethylene acts as a ligand that coordinates to the platinum metal.

3. **Effect of Coordination on Bond Length:**
- When ethylene coordinates to a metal center, the metal donates electrons to the anti-bonding π* orbitals of the ethylene. This interaction affects the bond order of the C-C bond.

4. **Bond Order and Bond Length Relationship:**
- The bond order is inversely proportional to bond length. As the bond order decreases, the bond length increases. In the case of C₂H₄ coordinating with platinum, the bond order of the C-C bond decreases due to the donation of electrons.

5. **Conclusion on C-C Bond Length in Zeise's Salt:**
- Since the bond order of the C-C bond in Zeise's salt is lower than that in isolated C₂H₄, the C-C bond length in Zeise's salt will be greater than \( x \).

6. **Final Answer:**
- Therefore, the bond length of the C-C bond in C₂H₄ when coordinated in Zeise's salt is greater than \( x \).
