state difference between pi bond and sigma bond?
Answers
Explanation:
Sigma bond is a chemical bond formed by the linear or co-axial overlapping of the atomic orbitals of two atoms. A pi bond is a type of covalent bond that exists between atoms where the electrons are on top and bottom of the axis connecting the nuclei of the joined atoms.
Sigma bond :
- Sigma bond is formed due to the axial overlapping of two atomic orbitals.
- these bonds are stronger.
- it can exist independently without pi bonds.
- allows free rotation.
- it is formed at first when atoms interact.
- it determines the shape of the molecule.
Pi bonds :
- Pi bonds are formed by lateral overlapping of half filled atomic orbitals.
- these bonds are weaker than sigma bond.
- they can only exist along with sigma bond.
- restricts free rotation.
- it is formed between two atoms after the formation of sigma bonds.
- it doesn't determine the shape of the molecule.
