Hydrogen peroxide vs rubbing alcohol. Hydrogen peroxide and rubbing alcohol are both disinfectants and commonly used for house hold cleansing purposes. Hydrogen peroxide is a compound formed by the combination of oxygen and hydrogen whereas rubbing alcohol is a very poisonous form of ethyl alcohol or simply put alcohol. Both are placed in the same kit and practically used for same purposes but they are very different chemically and have very different properties.
The more oxygen atoms and hydrophilic functional groups the molecule has, the more hydrophilic the molecule is. Ethanol or ethyl alcohol C2H5OH has a hydroxyl group in place of one of the hydrogens in ethane. Ethanol is a liquid and attracted to water molecules (Hydrophilic). Ethanol of course is drinking alcohol that hopefully you use in moderation. Acetic acid has a carboxyl group (COOH). Carboxyl groups are sometimes called organic acid groups because compounds with carboxyl groups donate hydrogen ions to a solution.
