- Molecular polarity results from inherent geometrical factors in a given combination of atoms. Let us consider water, the most common example of a polar molecule. There is an oxygen atom in the middle, attached to two hydrogen atoms. Why are these hydrogen atoms arranged at an approximately 120o angle to each other, creating a polar molecule, rather than at a 180o angle which would create a non-polar molecule? It's because the oxygen atom has a full outer shell of electrons, when it bonds to the hydrogen atoms, and that means eight electrons forming four pairs of electrons. These four pairs of electrons repel each other (as described by Coulomb's Law) and they therefore assume positions as far apart from each other as possible, which turns out to be the corners of a tetrahedron. The two hydrogen atoms each share one of the electron pairs, so they must go where the electrons go. But since they also have a positive nucleus, they create an unbalanced or polar electrical charge in the molecule.
What else can I help you with?
If polar and nonpolar solutions are mixed together they will form what?
If polar and nonpolar solutions are mixed together, they will not mix and will form separate layers due to their different polarities. This is because polar molecules are attracted to other polar molecules, while nonpolar molecules are attracted to other nonpolar molecules.
What type of molecules dissolves in water polar or nonpolar?
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
Molecules that form when electrons are shared unequally between atoms are called?
Valence electrons
What kinds of molecules do water dissolve?
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have dipole-dipole interactions with.
Why do charged and polar molecules dissolve in aqueous solutions?
Charged and polar molecules dissolve in aqueous solutions due to their ability to interact with the polar water molecules through electrostatic interactions. The partial charges on these molecules allow them to form hydrogen bonds with water molecules, which helps them become evenly dispersed throughout the solution. This enables them to dissolve and form a homogenous mixture with water.

Ionic bonds form between molecules that have what?
Polar molecules

Valence electrons
Does Cl have polar interaction between molecules?
The anion Cl- form ionic bonds in molecules.
Which of these molecules is polar?
Which of these molecules is polar
What are lipids of large molecules?
Lipids are fats, or to be technical, they are non-polar organic molecules. They do form large molecules but they do not polymerize.
Do polar molecules form hydrogen bond when they dissolve in water?
yes
Is sugar immiscible in water?
No, sugar is soluble in water, which means it can dissolve into water to form a solution. Sugar molecules are polar, allowing them to form bonds with the polar water molecules, resulting in a homogeneous mixture.

Why do oil and water hate each other?
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
