A triple bond between two carbon atoms is composed of one.......... and ........... bonds

Answer

To answer the question about the composition of a triple bond between two carbon atoms, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding the Structure of a Triple Bond**:
- A triple bond between two carbon atoms consists of three bonds in total.

2. **Identifying the Types of Bonds**:
- In chemistry, there are two main types of covalent bonds: sigma (σ) bonds and pi (π) bonds.
- A sigma bond is the first bond formed between two atoms and is characterized by the head-on overlap of atomic orbitals.
- Pi bonds are formed by the side-to-side overlap of p orbitals and can exist in pairs.

3. **Composition of the Triple Bond**:
- In a triple bond, one bond is a sigma bond (σ) and the other two are pi bonds (π).
- Therefore, the composition of a triple bond between two carbon atoms can be summarized as:
- 1 sigma bond (σ)
- 2 pi bonds (π)

4. **Final Answer**:
- A triple bond between two carbon atoms is composed of one sigma bond and two pi bonds.
