PPT-Alcohols Alcohols are some of the most important molecules in organic chemistry.

Uses of Alcohols Ethanol CH₃CH₂OH   Ethanol is a solvent its a widely safe solvent so used to dissolve many organic compounds that are insoluble in water especially for medicine to extract active constituents from inert parts of crude drugs .
