Differentiate between pi and sigma bond |
| Answer» Pi bond is weak bond but sigma bond is strong bond and pi bonds are formed by side to side overlapping but sigma bond is formed by head to head overlapping<br>Pi bond exist independently but sigma bond not exist independently it always exist with pi bond and pi bond is stronger than sigma bond<br>bond = Formed by lateral or side wise overlapping of atomic orbitals such that direction of overlap lies perpendicular to the axisσ bond = Formed by axial overlapping or end to end overlapping of atomic orbitals, along internuclear axis. It is more of stronger.<br>σ bond = Formed by axial overlapping or end to end overlapping of atomic orbitals, along internuclear axis. It is more of stronger. There is proper distribution of electron density across the internuclear axis. Present mostly as SINGLE bonds between atoms. π bond = Formed by lateral or side wise overlapping of atomic orbitals such that direction of overlap lies perpendicular to the axis. It is more weaker than σ bonds. They are usually present as multiple bonds alongside single bonds. Electron density is distributed in an unorganized manner. | |
