    Describe the structure of water and it's dipolar nature.
    I understand that it is a covalent bond between 2 hydrogen atoms and 1 oxygen atom and that the dipolar nature causes a slightly negative charge on the oxygen and slightly positive on the hydrogen but I have no clue why and I'm not sure what answer they are looking for. Help please.

    Thats more chem than Bio really, where did you get that Q from, i finished A-level BIo and was never asked that, though it would have been easy to answer, since i did chem.
    oxygen is more electronegative than Hydrogen, so pull electrons to it. This makes it partially negative and the H partially positive, most thing are dipolar due to bonds and electronegativity, i could go into more detail but thats the jist... not sure what you need really, its not hard to understand in Chem, but if your not doing chem i dont see why you need to know about it.

    This is taken directly from our syllabus
    Water Understand the importance of the dipole nature of water leading to hydrogenbonding and the significance of the following to organisms:
    • ● high specific heat capacity
    • ● polar solvent
    • ● surface tension
    • ● incompressibility
    • ● maximum density at 4 °C.
      our teacher set the questions saying;Explain how the structure of water determines it's properties and their significance to organisms.

    what exam board is this ?
    I did do the old syllabus, but thats honestly such a stupid question to ask of a BIO student, BIO was the easy science, why did they have to go **** it up for the next years.i mean that knowledge would have given 0 help to the BIO i learnt from AS-A2.. and some of that you would need basic a2 chem to fully understand, though AS chem would be enough, i dont see how GCSE chem could let you understand that ... though i guess youre now learning it in BIO, but like i said, its pretty useless to learn.

    I didn't even get asked this at A2 chem, but it could be to do with the fact that water forms hydrogen bonds with other water molecules, due to its dipolarity (that a word..?) which causes it to express other characteristics like high surface tension/cohesion/adhesion

    It's dipolar (di = two) because the oxygen is more electronegative than the hydrogen, so the hydrogen atom is electron-deficient in the O-H bond.

    This then means that as there are two O-H bonds in a molecule of water, it is dipolar.
