Marvelous Methanol

Methanol is a useful molecule!
Methanol can also be called wood alcohol. It is biodegradable, it evaporates quickly, and under ordinary conditions it is stable. Classified under Solvent Group 2, methanol has a boiling point of 64.5 degrees Celsius and a melting point of -98 degrees Celsius. Also, Methanol contains all three types of forces: Hydrogen Forces, Dipole-Dipole, and London Dispersion Forces! It's shape is a tetrahedron!Everyday we use methanol! The picture below shows how we use methanol everyday!

It can be used as an industrial solvent and is a vital component in creating materials such as:
  • Streptomycin 
  • Vitamins
  • Hormones
  • Polymers
  • Plastics 
  • Paint strippers
Methanol is used as an antifreeze in pipelines and windshield washer fluid because it is able to reduce the freezing point of the substance. 
Methanol can even extend the life of gasoline! Through methanol injection, when methanol is mixed with water, the power of a diesel engine is increased and the exhaust gas temperature is decreased. 
This marvelous product is so amazing because we use it everyday! It is an industrial solvent, it is a necessity in windshield washer fluids and pipelines and it is a great way to extend the use of gasoline! Don't forget about it's interesting properties!

Make a MARVELOUS choice! Purchase Methanol!

WARNING: Methanol should not be consumed, it is poisonous
Methanol is great for fuel, not for food!

Inter-Molecular Forces

  

*Note: Methanol also has London Dispersion Force 
Force Types are described below. 

Force Descriptions

London Dispersion Force- a very temporary, uneven distribution of electrons, creating a temporary dipole. It forms a week bond between two molecules.

Dipole-Dipole- an electrostatic attraction between the negative side of one molecule and the positive end of the other molecule. In the Methanol molecule there is a dipole-dipole force between the oxygen of one molecule and hydrogen of another. It is represented by a doted line. 


Hydrogen Force-a special type of dipole-dipole that forms a temporary covalent bond. A hydrogen bond forms between hydrogen and oxygen, hydrogen and nitrogen, or hydrogen and fluorine. In Methane it forms between the hydrogen of one molecule and the oxygen of another molecule. It is represented by a solid line. 


Methanol has all three types of forces.
