Answer 1

Answer:

Sigma bond is a chemical bond formed by the co-axial or linear overlapping of atomic orbitals of two atoms. 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 bonds are formed by end-to-end overlapping and Pi bonds are when the lobe of one atomic orbital overlaps another.

pi bond is stronger and sigma is weak bond

simga decide the shape of molecule and pi decides the length of molecule

Answer 2

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.
