What causes water molecules to be attracted to each other?

A. Polar covalent bonds inside each water molecule
B. Hydrogen bonds inside each water molecule
C. Ionic bonds between water molecules
D. Nonpolar covalent bonds between water molecules

Respuesta :

This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

  • Water is a polar protic molecule.
  • Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
  • Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
  • In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
  • So, both option (A) and (B) are correct
