Question

Difference between sigma bond and pie bond?

Answer 1

Sigma bond are the first one who made in between two atom it is hybridize band and Pi bond are the second and third Bond which is made between two atom.

Answer 2

✨Heya!!!!✌

✍Your answer⬇⬇⬇⬇

⭐Sigma-bond⤵

➡The bond is formed by the overlapping of orbitals along their axes(end to end overlap). It includes s-s,s-p, and p-p overlapping).

➡It is a strong bond.

➡Electron cloud is symmetrically about the line joining the two nuclei.

➡There can be free rotation of atoms around this bond.

➡These are less reactive.

➡The shape of the molecule is determined by these bonds.

➡Sigma-electrons are referred as localized.

➡Sigma-bond can have an independent existence.

⭐π-bond⤵

➡The bond is formed by sidewise overlapping of orbitals(lateral overlapping). It includes p-p overlapping.

➡It is a weak bond.

➡Electron cloud is unsymmetrical.

➡Free rotation is not possible around this bond.

➡These are more reactive.

➡These bonds donot affect the shape of the molecule.

➡π-electrons are referred as mobile electrons.

➡π-bond always exists along with a sigma-bond.
