The higher electronegativity of oxygen allows water to carry partial charges (negative on oxygen, positive on hydrogen).
These partial charges allow water to bind strongly with itself, and allows it to interact with polar molecules. The partial charge allows polar molecules to dissolve in water.

Why is water polar?
Water is a polar molecule formed by atoms which have different electronegativities, the atom with the highest level of electronegativity, bonds with the less electronegative atoms. The electronegativity of Oxygen is 3.5 whereas Hydrogen has an electronegativity of 2.20, therefore the difference is 1.4 allowing water to qualify as a polar covalent bond.

Why does the oxygen side of a water molecule have a partial negative charge and the hydrogen side of a water molecule have a partial positive charge?
Because the oxygen electronegativity is greater than the electronegativity of hydrogen.
How is water a polar molecule in terms of electronegativity?
Because there's a lot of difference in electronegativity between H and O, so that molecule will be polar
How do polar bonds affect the polarity of a molecule?
This question is reversed in terms of the correct cause and effect relationships. Polarity of the molecule is driven by electronegativity, with the oxygen in water as a prime example. In turn this electronegativity causes the bend in the water molecule and thus its characteristic dipole moment. This moment serves to allow hydrogen bonding. This is the core relationship between polar bonds and molecular polarities.

What would be the effect on properties of water molecule if oxygen and hydrogen had equal electronegativity?
The attraction of a particular kind of atom for the electrons of a covalent bond is called its electronegativity. If oxygen and hydrogen had equal electronegativity there wouldn't be any attraction between each molecule of water thus no hydrogen bonds.
