    What do you know about polar solvents and non-polar solvents?

    Mainly polar solvent are miscible with water whereas nonpolar ar not miscible with water.
    &polar solvent usually has OH BOND, nonpolar has CO BOND.
    Charges ar unequally distributed in polar solvent , in nonpolar equally distributed. Thatis I KNOW ONLY THIS MUCH.

    Hm... nonpolar doesn't necessarily have CO bond, because CO by itself is polar!

    By definition, a non-polar substance doesn't have any resultant polarity, that is the positive and negative charges cancel each other out. This happens when the centre of charges in a molecule coincide.

    But here, what you need to know is that:
    Polar solutes dissolve in polar solvents only.
    Non-polar solutes dissolve in non-polar solvents only.

    H2SO4 is a polar solute.
    Hexane is a non-polar solvent.

    Hence, they don't dissolve in each other.
