what is pi bond and sigma bonnd
Answers
Answer:
The covalent chemical bonds, in each of which two lobes of an orbital overlap with two lobes of an orbital on another atom, in which overlap occurs laterally is called pi bond.
The most simple definition for diatomic molecules using the language and tools of symmetry groups is called sigma bond.
Answer:
Pi bond - It's a covalent bond formed by the sidewise overlap of atomic orbitals.
Sigma bond - It's a bond formed by axial overlapping of half-filled orbitals.
Explanation:
The electrical cloud formed the sigma bond is cylindrically symmetrical. The electrons that take part in sigma bond formation are called sigma electrons. Three types of sigma bonding are possible - s-s overlap, s-p overlap, p-p overlap. The p-p overlap is stronger than the s-s overlap.
In the pi bond, the overlap happens in such a way that the orbital overlap takes place in a way that their axes are parallel to each other but perpendicular to their internuclear axis. The electrons that take part in the pi bond formation are called the pi electrons.
