|Common Functional Groups - Alcohols|
|The alcohol functional group is an -OH. The polar oxygen gives the molecule properties of solubility with other polar solvents such as water. It's polar properties also cause the molecules to stick together by electrostatic attraction more readily. Ethane is a gas at room temperature whereas ethanol (ethyl alcohol) is a liquid at room temperature.|
|eg. CH3CH2OH ethanol (ethyl alcohol).|
|The parent name is kept and the "e" from ethane was dropped and
replaced by "ol". Alcohols are more important than double or triple bonds.
If both an alcohol and a double and/or triple bond appear in a molecule
then name it as an alcohol. If something more important than alcohol is
in a molecule the alcohol gets named as "hydroxy" and a number just like
any other attached group.
