Water has a tetrahedral electron group geometry. On a water molecule, two of the tetrahedron corners are occupied by lone pairs (totaling four nonbonded electrons) and on the other two corners are hydrogen. Since oxygen is very electronegative, it strongly pulls the electrons away from the two hydrogens. This leaves the hydrogen protons relatively exposed and gives a positive charge to the hydrogen corners.
On the opposite corners, there are nonbonded lone pair electrons. That is, there are "extra" negative charges opposite of the hydrogens. So, a molecule of water has a partial positive charge on two corners and partial negative charge on the other two corners. This gives water a significant dipole moment.
Of course, these aren't real corners, it is just convenient to describe it this way.

What do you call a hydrate when it has lost its water moecules?
When a hydrate loses its water molecules, it is called an anhydrate.
Is it true When water dissolves sugar the positive ends of the water moecules are attracted to the negative ends of the sugar molecules?
Generally, when a molecule is dissolved in water, the process called hydration occurs. This process consists in the creation around the polar or ionic parts of the dissolved molecule of a shell of water molecules that are bonded to solute via polar bonds (called hydrogen bonds). This is a fundamental process in solution formation. As a matter of fact, it deeply influences the spontaneous solution formation by participating to the solution free energy and renders the water a very good solvent, differently from other liquids that are not able to form such bonds.
Is tap water polar or non polar?
Water is polar molecule. Since oxygen has a higher electronegativity than hydrogen.
Does polar or non polar dissolve in water?
Polar substances dissolve in water because they have similar polar characteristics that allow them to interact and mix well. Non-polar substances, on the other hand, do not dissolve in water because water is a polar molecule and cannot effectively interact with non-polar molecules.
Is coconut water non-polar?
Coconut water is primarily water, which is a polar molecule due to its asymmetrical distribution of charge. Therefore, coconut water is not non-polar.
What happens if water is a polar molecule?
Water IS a polar molecule.
Could Water be a polar molecule?
Water is a polar molecule.
Are polar molecules soluble in water?
No. Water is polar, and only dissolves other polar things.
Is water composed of polar bonds?
Yes, water has polar bonds, and is a very polar molecule.
Why does NaCl dissolve in water?
Water is polar. NaCl is polar. Polar substances are soluble in polar solvents.
What type of molecules interact with water polar or nonpolar?
Polar molecules interact with water because water is a polar molecule itself. Nonpolar molecules do not interact with water because they do not have regions of positive and negative charge like polar molecules do.
