What does hydrogen bonding do to polarity?
The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. ... As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds.
What affects bond polarity?
Summary. The electronegativity of an atom determines how strongly it attracts electrons to itself. The polarity of a bond is affected by the electronegativity values of the two atoms involved in that bond.
