    Answer: Option A, B, D and F.

    Explanation:

    Water is a universal solvent I. e everything dissolves in it. Water molecules consist of an oxygen atom and two hydrogen atoms linked by covalent bond. The oxygen atom is electronegative and it tends to attract more electrons to itself, there is unequal sharing of electrons which make the oxygen slightly negatively charged and hydrogen slightly positively charged, making it polar molecules I. e unlike charges attract each other. Electrons in the covalent bond spend more time around oxygen atom and less around hydrogen atoms.

    F: The oxygen atom has a greater attraction for the electrons in the surrounding covalent bonds than the

    hydrogen atoms.

    Explanation:

    Between hydrogen and oxygen atoms exist a covalent bond. Oxygen is more electronegative than hydrogen atom hence its ability to get attracted to itself more electrons than hydrogen.
