Polar or Nonpolar?

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. 


-*Another way to determine polarity is through drawing lines of symmetry. To be symmetrical, the line drawn must cut the molecule in "half", or in other words, you are able to see a mirror image. If 0 or only 1 line of symmetry can be drawn through the drawing (Lewis Structure) of the molecule, then it is polar. If 2 or more lines of symmetry can be drawn, then the molecule is nonpolar.
