Describe what condition exists in water molecules to make them dipolar.

The straight geometry of the water molecule gives a slight positive charge to the oxygen side of the water molecule and a slight negative charge to the hydrogen side of the water molecule. This slight separation of charges gives the entire molecule an electrical polarity, so water molecules are monopoles.

The straight geometry of the water molecule gives a slight overall negative charge to the side of the oxygen atom and a slight overall positive charge to the side of the hydrogen atoms. This slight separation of charges gives the entire molecule an electrical polarity, so water molecules are dipolar.

The bent geometry of the water molecule gives a slight overall negative charge to the oxygen side of the molecule and a slight overall positive charge to the hydrogen side of the molecule. This slight separation of charges gives the entire molecule an electrical polarity, so water molecules are dipolar.

Final answer:

Water molecules are dipolar because of the asymmetrical distribution of charges due to their bent shape and the electronegativity difference between oxygen and hydrogen, which results in a net dipole pointing towards the oxygen atom.

Step-by-step explanation:

Water molecules are dipolar due to their bent molecular structure, which arises from the two bonded hydrogen atoms and two lone pairs of electrons on the central oxygen atom. The electronegativity difference between the oxygen and hydrogen atoms creates individual O-H bond dipoles that point towards the more electronegative oxygen atom. Because of the geometry of the molecule, these dipoles do not cancel out, leaving one side of the molecule with a slight negative charge (the oxygen side) and the other side with a slight positive charge (the hydrogen side). This separation of charge makes water a polar molecule with a net dipole pointing towards the oxygen atom.
