Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
oxygen is more electronegative than hydrogen
so oxygen pulls the shared paired of electrons towards it.
because it doesnt want to
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
A negative charge that exists because of a covalent bond with hydrogen
Water is a good solvent due to its polarity. The single Oxygen molecule and two Hydrogen molecules do not share electrons equally, the Oxygen molecule takes precedent over the Hydrogen molecules. The Polarity and in some small part, the small molecular size makes water the, "Universal Solvent".
The water is a polar molecule because it is not equally charged. Its half side has a positive charge and the other half has a negative charge. because the electrons spend more of their time with the oxygen and not with hydrogen and due to this they get more negative charge and due to this the water is a polar molecule.---------------------------------------------------------------1. The water molecule is not linear.2. Oxygen is more electronegative than hydrogen.3. As a consequence the hydrogen atoms are slightly positive and the molecule is polar.

In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.

The oxygen and hydrogen in water are bonded by a covalent bond. This means that the two lone lone electrons of hydrogen are shared with oxygen. Oxygen has a tendency to "hoard" electrons. So when it bonds with the hydrogen the two shared electrons are closer to the oxygen than to the hydrogen. As a result one side of water(the one with the oxygen) becomes slightly negative due to the fact that the oxygen has the two electrons closer to it. The side of the hydrogen becomes slightly positive as a result. When two or more molecules of water are placed together the slightly negatively charged oxygen from one molecule attracts the slightly positively charged hydrogen from another molecule forming a weak hydrogen bond. this hydrogen bond is formed as a result of the polarity of water.
Oxygen attracts electrons more strongly than hydrogen does.
A negative charge that exists because of a covalent bond with hydrogen
In a water molecule, oxygen (which is a quite more electronegative than hydrogen), tends to attract electrons close to it, so it gets a residual negative charge, while hydrogen gets positively charged.That's the reason why water has a high boiling temperature, because water molecules establish electrostatic bonds, between the oxygen and hydrogen from different molecules, creating a kind of net of interactions, which make it harder to evaporate it.
