Water is a "bent" molecule. The angle between the the two O-H bonds is 104 and a half degrees (i.e. well below the 180 degrees that would make it linear). Each O-H bond is polarized. That is, the bonding pair of electrons in each O-H bond is shifted markedly towards the O atom. Each O-H bond thus has a dipole moment. If the molecule was linear, these dipoles would cancel each other out and the molecule would be non-polar. However, there are 2 pairs of non-bonding electrons on the central oxygen atom which are held closer to the O nucleus than are the bonding pairs. These lone pairs of electrons cause more repulsion between each other than do the bonding pairs, which explains why the molecule is bent rather than linear. Because it is bent, the dipoles do not cancel each other out and there is an overall dipole moment vector, meaning that the molecule itself is polar.

Is CH3OH polar or non polar?

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.


What is unequal sharing of electrons within a water molecule?

water is a polar, covalent molecule. it doesn't have an unsharing molecule. its also has to do with the 8 properties of water.


Would a molecule with polar covalent bonds be soluble in water?

Yes, in chemistry polar molecules are soluble with other polar molecules. You know that water is polar because of it's structure. Two hydrogens are bonded the an oxygen. The oxygen has two lone pairs of electrons that cause the molecule to have a bent VSEPR structure. This creates a net dipole due to the high electronegativity of oxygen. Essentially, the oxygen is slightly negative and the hydrogens slightly positive. So, yes your polar molecule is soluble with water (also polar).


Is water non-polar?

All heteroatomic molecules are polar it depends on the structure of overall molecule to know whether the whole molecule is polar or not, water is polar cuz dipole between Hydrogen and Oxygen and that between Oxygen and lone pair don't cancel each other.


Is a polar molecule is a molecule with the ability to resists changes in temperature?

A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.

How to know if a substance is a polar or not?

First of all you have to draw the Lewis dot structure of the molecule. If the molecule is symmetrical, it's non-polar. If the molecule is non-symmetrical or asymmetrical, then the molecule is polar.
