How many sigma and pie bonds present in cyclohexane ?
Cyclohexane is a cyclic hydrocarbon with the formula C6H12. It consists of a ring of six carbon atoms, each bonded to two hydrogen atoms. To determine the number of sigma and pi bonds present in cyclohexane, we need to understand the bonding in the molecule.
Cyclohexane is a saturated hydrocarbon, meaning it contains only single bonds. It adopts a chair conformation, which is the most stable form for the molecule. In this conformation, each carbon atom is bonded to four other atoms, resulting in a total of 24 sigma bonds in cyclohexane.
Here is a breakdown of the sigma and pi bonds in cyclohexane:
1. Sigma Bonds:
- A sigma (σ) bond is formed by the overlap of two atomic orbitals along the axis connecting the two bonding atoms. It allows free rotation around the bond axis.
- In cyclohexane, each carbon atom is bonded to two adjacent carbon atoms and two hydrogen atoms, resulting in six sigma bonds per carbon atom. Since there are six carbon atoms in cyclohexane, the total number of sigma bonds is 6 x 6 = 36.
2. Pi Bonds:
- A pi (π) bond is formed by the overlap of two parallel p orbitals. It restricts rotation around the bond axis.
- In cyclohexane, there are no pi bonds. This is because all the carbon-carbon bonds are single bonds, which involve the overlap of only sigma orbitals. The ring structure of cyclohexane does not allow for the presence of pi bonds.
In summary, cyclohexane contains 36 sigma bonds and no pi bonds. The molecule adopts a stable chair conformation, with each carbon atom bonded to four other atoms. The absence of pi bonds in cyclohexane is due to the nature of its structure, which does not allow for the presence of double bonds.
