Question

four difference between sigma and pie bond

Answer 1

Single bond contains one sigma bond, whereas double bond contains onesigma bond and one pi bond. ... The main difference between a sigma and a pi bond lies in the overlapping of the orbitals. The sigma bond is formed by axial overlapping of orbitals and pi bond is formed by lateral overlapping of orbitals.

Answer 2

A single bond is a sigma bond. A double bond is a sigma bond plus a pi bond. A triple bond is one sigma and two pi bonds. 


A sigma bond is your basic head-on covalent bond, with the bond in line with the bonding orbitals. You can only ever have one sigma bond between any two atoms.

A pi bond is a covalent bond between orbitals perpendicular to the bond direction, usually p-orbitals (never s). The resulting bond is roughly shaped like two croissants with the tips touching at the bonded atoms. Pi bonds do not allow rotation around the bonding axis due to this geometry. 


A second pi bond (the third bond in a triple bond, or a second double bond to another atom) is always perpendicular (orthogonal) to the first one. In other words, if the sigma bond is on the x axis, one pi bond will form between orbitals on the y axis and another will form between orbitals on the z axis.
