Molecules can be grouped as polar or non-polar molecules. Some are also in between.
The arrangement or geometry of the atoms in some molecules is such that one end of the molecule has a positive electrical charge and the other side has a negative charge. If this is the case, the molecule is called a polar molecule, meaning that it has electrical poles. Otherwise, it is called a non-polar molecule.
Examples of polar molecules of materials that are gases under standard conditions are:
- Ammonia (NH3)
- Sulfur Dioxide (SO2)
- Hydrogen Sulfide (H2S).
Also, Ethanol is polar, since its oxygen molecule draws electrons towards it due to its high electro-negativity, causing a negative charge around itself. Water is also an example of polar molecule.
A non-polar molecule is one that the electrons are distributed more symmetrically and thus does not have an abundance of charges at the opposite sides. The charges all cancel out each other.
Most hydrocarbon liquids are non-polar molecules.
Examples of non polar molecules include:
- Toluene
- Gasoline
- Hydrogen (H2)
- Nitrogen (N2)
- Oxygen (O2)
- Carbon Dioxide (CO2)
- Methane (CH4)
- Ethylene (C2H4)
Carbon-di-oxide is also an example of non-polar molecule.
