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

Most of the alcohols are known to be colourless liquids or even are said to behave as solid at room temperatures Alcohols with less molecular weight are said to be highly soluble in water and with their increase in molecular weight they tend to become less soluble and their .
