Buy Acetone!

Acetone is:
- colorless with a strong odor
-produced when the human body uses fat instead of glucose for energy
- higly flammable!
- it is flammable, evaporates easily and dissolves in water
-damages kidneys, livers and nerves

A Product With Acetone
Acetone is found in nail polish remover!



The molecule C3H6O, also known as Acetone, is Triangular Planar. Its Lewis Structure is:

This atom is an AX3 or a Triangular Planar because there are no unshared pairs on the central atom and the central atom  has three other atoms haning off of it. The central carbon shares a double bond with the Oxygen and a single bond with the other Carbons. The two other carbons share three single bonds with three Hydrogens each.

Bond Angles

The red ball represents Oxygen. The black balls represent Carbon. The white ball repsesent the Hydrogens.

The molecule is a triangular planar molecule so the bond angles on C3H6O are 120 degrees. 

Polarity of the Molecule and its Bonds

Molecule Polarity
Acetone is a polar molecule. First of all, there is a double bond between the central carbon and the oxgen. The oxygen has two unshared electron pairs which make that end of the molecule highly negative. The bonds between the central Carbon to the other Carbons are single. Those Carbons both have bonds with three Hydrogens, which have a positive charge. The uneven distribution of charges througout the molecule makes it polar.

Bond Polarity/Electronegativity

2.5-2.2--->  0.3
 This bond is very covalent

3.5-2.5---> 1.0
 This bond is moderately covalent

Attractive Forces
If one Acetone came next to another Acetone there would be two attractive forces. These are:

London Dispersion Forces:An electrostatic attraction between the poitive end of a dipole and the negative end of another dipole.  

Dipole-Dipole Forces:A weak force of attraction between two molecules created by temporary dipoles caused by elections moving around two atoms.  This happens with all molecule because electrons are constantly moving

This molecule is not attracted to another molecule of Acetone by hydrogen bonding because although there are hydrogen molecules they are not bonded to an Oxygen, Flourine or Nitrogen.

Hydrogen Bonding: A special case of dipole-dipole where a covalent bond occurs between a hydrogen of one molecule and a Oxygen, Nitrogen or Fluorine of a different  molecule. 
However, if this molecule came across a molecule such as HF there would be hydrogen bonding because the Hydrogen of Acetone would form a bond with the Flourine of HF.
