Write the differences between sigma and pi bond
Answers
Answer:
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.
Answer:
sigma bond:
➡️A sigma bond is formed by the axial overlap of orbitals.
➡️extent of overlapping is more hence the bond is stronger.
➡️A sigma bond involves overlap pf s-s ,s-p, p-p orbitals.
➡️free rotation of atoms is possible across a sigma bond.
pi bond:
➡️A pi bond is formed by the side ways overlap of orbitals.
➡️ extent of overlaping is less hence the bond is weak.
➡️A pi bond involves the overlap of p orbitals only.
➡️ there is no free rotation of atoms across a pi bond.
