Question

Give explanation of σ and π bonds. Mention by overlapping of which orbitals are σ and π bonds are formed?

Answer 1

Hybrid orbital forms only sigma (σ bonds) σ and pi bonds (π bonds) are formed by unhybridised orbitals.

This is contrasted by sigma bonds which form bonding orbital directly between the nuclei of the bonding atoms, resulting in greater overlap and a strong sigma bond.

Pi bonds result from overlap of atomic orbital that are in contact through two areas of overlap.

Answer 2

Answer:

Sigma and pi bonds are types of covalent bonds that differ in the overlapping of atomic orbitals. Covalent bonds are formed by the overlapping of atomic orbitals. Sigma bonds are a result of the head-to-head overlapping of atomic orbitals whereas pi bonds are formed by the lateral overlap of two atomic orbitals.
