How many pi bonds are there in triple bonds?

In chemistry, a triple bond consists of one sigma (σ) bond and two pi (π) bonds.

Explanation:
Types of Bonds:

Sigma (σ) Bond: This is the first bond formed between two atoms. It is created by the head-on overlap of atomic orbitals. A sigma bond is always present in any type of bond (single, double, or triple).
Pi (π) Bond: This bond is formed by the sideways overlap of p orbitals. Pi bonds are present in double and triple bonds but not in single bonds.
Triple Bonds:

A triple bond is formed when two atoms share three pairs of electrons. For example, in the molecule nitrogen gas (N₂), the two nitrogen atoms are held together by a triple bond.
The breakdown of a triple bond is as follows:
1 σ bond: This is the first bond that forms and is the strongest.
2 π bonds: These bonds are formed after the sigma bond and result from the side-to-side overlap of p orbitals.
Conclusion:
Thus, in a triple bond, there are 2 pi bonds.

Example: The triple bond in acetylene (C₂H₂) is another common example where each carbon atom forms one σ bond and two π bonds with the other carbon atom.
