Homework Help: Melting Point

  1. Jul 13, 2005 #1
    Hi..
    I've finished this topic but I was confused in this question.

    The question is :

    The main reason for the high melting point of water compared to other group4 hydrides can be explained by:

    a.Ionic Bonding
    b.Covalent Bonding
    c.Dispersion Forces
    d.Hydrogen Bonding

    I'm not sure which it is.

    Thank you...

    First of all, water is not a group 4 hydride - it is a group 6 hydride.

    Ask yourself what kind of bonds (inter- or intra-molecular ?) you need to break in order to melt something.

    What do you mean by "I've finished this topic" ?

    yeah..

    i know that its one of the intermolecular forces but i cant figure which one it is. How do you figure that out??
    THANKS

    Which of those forces are intermolecular and which ones are intramolecular ?

    Read up in your chemistry text, on the section intermolecular attractions, it should have a whole section devoted to water specifically...yes it's easy as that
