Shortest C – C bond is present in

Options

A. `sp -sp`
B. `sp^2 - sp`
C. `sp^2 - sp^2`
D. `sp^3 - sp`

Explanation

To determine the shortest C–C bond, we need to analyze the types of carbon-carbon bonds and their corresponding bond lengths. Here’s a step-by-step solution:

### Step 1: Understand the Types of Carbon Bonds
Carbon can form three types of bonds with itself:
- **Single bond (C–C)**: This bond is formed by the overlap of two sp³ hybridized orbitals.
- **Double bond (C=C)**: This bond consists of one sigma bond (σ) formed by the overlap of sp² hybridized orbitals and one pi bond (π).
- **Triple bond (C≡C)**: This bond consists of one sigma bond (σ) formed by the overlap of sp hybridized orbitals and two pi bonds (π).

### Step 2: Analyze Bond Strength and Length
The strength of a bond is inversely related to its length. The stronger the bond, the shorter its length. The order of bond strength and length for carbon bonds is as follows:
- **C≡C (triple bond)**: Strongest and shortest
- **C=C (double bond)**: Intermediate strength and length
- **C–C (single bond)**: Weakest and longest

### Step 3: Conclusion
From the analysis, we can conclude that the shortest C–C bond is found in the **triple bond (C≡C)**.

### Final Answer
The shortest C–C bond is present in **C≡C (triple bond)**.
