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.
Hydrogen Peroxide is polar. A polar molecule is a molecule that has an uneven distribution of electrons, therefore its charge is unevenly distributed. The electrons in the oxygen of the molecule are more negative. This is found through the electronegativity table in which it states that Oxygen has an electronegativity of 3.5. Hydrogen has an electronegativity of 2.2. [[The larger the number, the more negative the element is.]] Therefore, the negatives and positives form the uneven distribution of electrons, making the molecule polar, even though the O-O bond is nonpolar because of the equal distribution of electrons.
