Which type of bond is present between carbon-carbon atoms in acetylene?

Options

A. Single covalent bond
B. Double covalent bond
C. Triple covalent bond
D. Electrovalent bond

Explanation

To determine the type of bond present between carbon-carbon atoms in acetylene, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: Acetylene is also known as ethyne, which is a hydrocarbon consisting of two carbon atoms and two hydrogen atoms.

2. **Understand the Bonding in Carbon**: Carbon has four valencies, meaning it can form four bonds with other atoms. It can achieve this by forming single, double, or triple bonds.

3. **Recognize the Structure of Acetylene**: In acetylene (ethyne), the two carbon atoms are connected by a triple bond. This means that each carbon atom shares three pairs of electrons with the other carbon atom.

4. **Determine the Type of Bond**: Since the bond between the two carbon atoms involves the sharing of electrons, it is classified as a covalent bond. Specifically, because three pairs of electrons are shared, it is a triple covalent bond.

5. **Conclusion**: Therefore, the type of bond present between carbon-carbon atoms in acetylene is a **triple covalent bond**.
