A polar covalent bond is where the electrons are closer to the Oxygen nucleus than the Hydrogen.

The answer here is B, H2O.

Answer:

B.H2O

Explanation:

polar covalent bond exists when atoms that have different electronegativity share their electron in a covalent bond.

Water (H20) has a polar bond, where oxygen has an electronegativity of 3.44 which is higher while the electronegativity of hydrogen is 2.20 which is lower than oxygen.

  • One atom has a stronger pull than the other one and this inequality in electronegativity leads to the polar bond they shared.
  • The inequality in electron distribution is what causes the bent shape of the water molecules.
