Which is a cause of polarity in water molecules? partial negative charge on the hydrogen atoms partial positive charge on the oxygen atom high electronegativity difference between oxygen and hydrogen low electronegativity difference between oxygen and hydrogen

Explanation:

Water is a polar solvent as the hydrogen and oxygen atom has large difference in their electronegativities.

Oxygen atom is highly electronegative as compared to hydrogen atom therefore, it pulls the electrons of hydrogen atom closer towards itself.

As a result, two poles will create forming a partial positive charge on the hydrogen atom and partial negative charge on the oxygen atom.

Thus, we can conclude that high electronegativity difference between oxygen and hydrogen is the cause of polarity in water molecules.

the correct answer is a

ok whats the question if not i cannot you i need question and need a thing to answer
