This is the difference of electronegativity between oxygen and hydrogen.
This is the polarity of the water molecule.
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
asymmetrical charge distribution
CH3OH is a polar molecule owing to the polarity rendered by the -OH group. Its structure can be thought of as very similar, if not exactly, to the water molecule, and the CH3- group decreases the polarity as compared to water.
bond polarity is the polarity particular bond within a molecule, while molecular polarity is the polarity of the whole molecule. take for example water (H20): you could find the bond polarity of each H-0 bond (polar covalent), or the polarity of the whole molecule together (polar, because the electronegativity of oxygen is higher than the hydrogen atoms)
Water is a versatile molecule because of its polarity.
This is the polarity of the water molecule.
The polarity of the water molecule is what makes water a great solvent. It called the universal solvent.
polarity
the unequal sharing of electrons
becase of the polarity in water it is ver soluble

The property of water that has made it such an effective solvent is the polarity of the molecule. It is highly polar.
asymmetrical charge distribution
The polarity of the water molecule is responsible for most of water's properties.
Sugar (sucrose) dissolves in water because it is a polar molecule, owed namely to its many -OH groups. Remember that water (H-OH) is a very polar molecule. Both molecules share the -OH group that contributes to their polarity.
CH3OH is a polar molecule owing to the polarity rendered by the -OH group. Its structure can be thought of as very similar, if not exactly, to the water molecule, and the CH3- group decreases the polarity as compared to water.
