explain why the boiling points of alcohols and phenols are much higher than those of alkanes, ethers, etc., of similar molecular mass. discuss the factors that are believed to determine the acidity of alcohols and phenols.
10 Αυγ 2022 · Its formula can be also written as CH 3 −CH 2 −OH or C 2 H 5 OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor.
Ethanol is a 2-carbon alcohol. Its molecular formula is CH 3 CH 2 OH. The structure of the molecule of ethanol is CH 3 −CH 2 −OH (an ethyl group linked to a hydroxyl group), which indicates that the carbon of a methyl group (CH 3 −) is attached to the carbon of a methylene group (−CH 2 –), which is
It examines in some detail their simple physical properties such as solubility and boiling points. Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Alcohols fall into different classes depending on how the -OH group is positioned on the chain of carbon atoms.
