Answer

To solve the question regarding the hybridization of triply bonded carbons, the bond length of carbon-carbon triple bonds, and the bond strength of carbon-carbon triple bonds, we can break it down into the following steps:

### Step 1: Determine the Hybridization
The hybridization of carbon atoms involved in a carbon-carbon triple bond (C≡C) is **sp** hybridization. This is because in a triple bond, one sigma bond and two pi bonds are formed. The sp hybridization indicates that one s orbital and one p orbital from each carbon atom combine to form two sp hybrid orbitals.

**Hint:** Remember that sp hybridization occurs when there are two regions of electron density around the central atom.

### Step 2: Measure the Bond Length
The bond length of a carbon-carbon triple bond (C≡C) is approximately **1.20 Å (angstroms)**. This indicates the distance between the nuclei of the two carbon atoms in the triple bond.

**Hint:** Bond lengths can vary slightly based on molecular environment, but typical values are often provided in textbooks or reliable sources.

### Step 3: Assess the Bond Strength
The bond strength of a carbon-carbon triple bond is about **825 kJ/mol**. This high bond strength indicates that a significant amount of energy is required to break the triple bond, making it one of the strongest types of carbon-carbon bonds.

**Hint:** The strength of a bond is related to the number of bonds between atoms; triple bonds are stronger than double or single bonds due to the presence of multiple bonding interactions.

### Summary of Findings
- **Hybridization:** sp
- **Bond Length:** 1.20 Å
- **Bond Strength:** 825 kJ/mol

### Final Answer
The hybridization of carbon in a carbon-carbon triple bond is **sp**, the bond length is **1.20 Å**, and the bond strength is **825 kJ/mol**.
