Boiling point question

  1. Apr 16, 2005 #1
    I think the answer is e). I don't think it is ammonia because of the hydrogen bonding between nitrogen and hydrogen. This will result in a higher boiling point. This is the same with Hydrogen flouride and water. However, the two organic molecules i'm not sure. I assume that since the alcohol is a polar molecule and thus have stronger dipole-dipole interactions thus, a higher boiling point. Am i correct? Thanks.

    Methanol exists at RT as a liquid. You are correct the notion of hydrogen bonding increasing the bp (not only for the inorganics but for methanol as well). And if you have a CRC Handbook of Chemistry and Physics, you will find that you are in fact correct.

    Thanks, i'm just wondering, what does CRC stand for?

    Not too sure if they've changed the definition, but originally CRC = Chemical Rubber Company:

    You can arrange the strength of intermolecular bonding-dipole dipole, hydrogen bonding, van der wall (low or high molecular weight), etc.......

    which one of the compounds has a low molecular weight, and would suspect to be nonpolar?

    Note that it is asking for the lowest boiling point-lack of intermolecular attaction.

    very nice
