Alcohol is a heterogeneous class of organic compounds. All alcohol contains one or more hydroxyl (OH) groups. Ethanol (ethyl alcohol) is the most famous member of the family.
The alcohol has a special place in the history of chemistry and the history of mankind. Ethyl alcohol is the most popular drug of all time, and cause of joy and tragedy. From the perspective of alcohol chemists offer various possibilities for the study and synthesis of new and valuable connections.
Hydroxyl groups
Defining characteristics of alcohol is a hydroxyl group presence he (OH). Hydroxyl polarization because oxygen is electronegative element. Namely, when the OH is bound to the carbon atom, electron bond will tend to spend more time closer to oxygen atoms from carbon atoms. This creates an imbalance of electric charge on the molecule is such that the negative region around the OH group a little more that the rest of the molecule.
Chemical polarity alcohol has important implications. Alcohol is generally absorbed in varying degrees in both polar and nonpolar solvents. It also makes alcohol a good solvent to dissolve itself capable of various compounds. OH groups provide an opportunity for many synthetic reactions.
