    Default polarity of dichloromethane

    I've heard a lot of varying opinions about the polarity of CH2Cl2, dichloromethane. It has tetrahedral geometry, so the 2 C-Cl dipoles do not cancel each other out. However, I've seen DAT software list CH2Cl2 as a nonpolar molecule, and other sites saying it's slightly polar, but classified as a nonpolar molecule. What standard should I use when taking my test? Thanks!

    As an organic solvent we often use it as the organic layer (like in extractions) and it is relatively low in polarity, dissolving a variety of organic compounds. However, if asked in a general chemistry context whether it is polar or nonpolar, choose polar as the bond dipoles don't perfectly cancel as you pointed this out.

    Hope this helps!
