Question

Name a molecule which does not have π bond in it?

Answer 1

`H_2O` among many others

Explanation:

A molecule without a `pi` bond essentially means that it does not contain any double or triple covalent bonds, as a double covalent bond contains one `sigma` and one `pi` bond, and a triple covalent bond contains two `pi` and one `sigma` bond.

We have more molecules e.g
`NH_3`(ammonia)

`CH_4` (Methane)

`HCl` (hydrochloric acid)

Any molecule only containing only containing single covalent bonds, basically.
