Organic molecules

Alcohols: Any organic compound in which the hydroxyl functional group (-O H) is bound to a saturated carbon atom.

The term alcohol originally referred to the primary alcohol ethyl alcohol (ethanol), the alcohol in alcoholic beverages.


Methanol, wood alcohol,  methyl alcohol – CH3OH (MeOH).
The simplest alcohol

Ethanol, ethyl alcohol, drinking alcohol – produced by the fermentation of sugars by yeasts. – CH3CH2OH C2H5OH, EtOH

Isopropyl alcohol


Used widely as a solvent and as a cleaning fluid, especially for dissolving oils.

Chemical reaction involving alcohol

Dehydration Synthesis : how to make pear flavoring.

propyl alcohol + and acetic acid -> H2O + Propyl acetate ( CH3COOCH2CH2CH3)

Here are 3 ways of representing the molecules:

Top row = space-filled models. They show the space that each atom takes up.

Middle row = structural formula -> shows the atoms and approximate structure

Bottom row = skeletal structure. Chains of C atoms are simply drawn as lines (every bend in a line is a C. C atoms also at end of line, if no other element indicated. Less accurate shape, but easy to draw.
