    Firstly, what molecular features determine a molecule's melting point?

    the forces:
    hydrogen
    dipoole-dipole
    london dispersion

    I am thinking C. am i right?

    Your are correct, but do you know why?

    i believe B and C are dipole-dipole forces, which are stronger than A and D which are london disperion forces. i know dipole-diople is stronger than london. Would the answer be C since it has the longest carbon chain that is polar.

    thanks

    Keep working at it... "C" (1-butene) is NOT CORRECT!

    In which case, I stand corrected. I guess I should stick to Math & Physics, and butt out of chem....:redface:

    I did some research and i believe that the answer is A.

    does that sound right?
