Question

Which statement is true about the electrons in each polar bond of a water molecule?
They are more attracted by the oxygen atom than by the hydrogen atom.
They are more attracted by the hydrogen atom than by the oxygen atom.
They are equally attracted by the hydrogen and oxygen atoms.
They are equally repelled by the hydrogen and oxygen atoms.

Answer 1

They are more attracted by the oxygen atom than by the hydrogen atom.

Oxygen is significantly more electronegative than hydrogen, so the bonding electrons in each O–H bond are drawn closer to oxygen, giving O a partial negative charge and the H atoms partial positive charges.
