Respuesta :
Opposite ends have opposite charges.
Explanation:
Oxygen is more electronegative than hydrogen so the electrons of the covalent bonds spend more time closer to oxygen than hydrogen. ... They are linked by hydrogen bonds holding the substance together.

Answer:
B. opposite charges
Explanation:
Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.
Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
