Answer to Question #300478 in Physical Chemistry for Fafa

Question

Make a creative story about the lesson of the polarity of molecules

Answer 1

Microscopic world is mesmerizing. It has different types of characters, some who are introvert and others who are extrovert.

The extroverts are amiable, friendly, outgoing and social, especially with water.

A well known extrovert is H₂O molecules, but there are others like Ethanol also known as C₂H₅OH , another one is smelling salts (NH₃) and its a character adored by human beings because its perfume is used to restore or stimulate senses. Other extroverts are sulphur dioxide (SO₂) and Hydrogen sulphide (H₂S).

What is common with these microscopic characters that make them attracted to water is their shape (Geometry). One part of them usually has a positive charge, while the opposite end has a negative charge, and their beautiful shape is known as polar.

That is not the end of the story, though, for a molecule to be polar it needs to have polar bonds and it needs a net dipole moment. This is a fancy way of saying that the electrons need to be shared in one direction.

Next time you see a substance just blending with water to form a homogeneous arrangement, then know it is very social and it is liked by water.
