Question

What are sigma and pi bonds?

Answer 1

Sigma bonds are head-on, strong covalent bonds, while pi bonds are side-on connections and much weaker.

Explanation:

`sigma` (sigma) and `pi` (pi) bonds are types of covalent bond, where orbitals overlap or share electrons between non-metal atoms.

In a `sigma`-bond, the two orbitals have a head-on overlap, sharing electrons directly in one large, merged orbital.

`pi`-bonds are side-on connections, since they can't occupy the same head-on space as the `sigma`-bond. Because they are more indirect, `pi`-bonds are the weaker form of covalent bond.
