Question

Difference between sigma and pi bond class 11

Answer 1

A sigma bond is formed due to the head-on overlap between atomic orbitals. It is usually defined for diatomic molecules. This bond is the strongest covalent chemical bond. A pi bond is a bond formed due to the overlap of the orbital path of electrons. This bond is weaker than a sigma bond.

A single bond is always a sigma bond. On the other hand, a double bond has one sigma bond and one pi bond. Similarly, a triple bond has one sigma bond and two pi bonds.

Answer 2

hlo mate here is ur answer

SIGMA BOND

*It is formed by end - end on overlap of orbitals .

* It has independent existance .

* It is a strong bond . Because axial overlap is more .

* There can be only one sigma bond between atoms .



Pi BOND



* It is formed by lateral overlap of orbitals .

* It has no independent existance .

* It is a weak bond . Because lateral overlap is less.

* There can be one or two pie bonds between two atoms .
