A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms
AnswerA water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.

Wax does not dissolve in water since it is wax and?
Wax is hydrophobic, meaning it repels water molecules and does not mix with water. This is because wax molecules are non-polar, while water molecules are polar. The polar nature of water molecules makes it difficult for them to interact with non-polar molecules like wax.
What types of substances dissolve in water?
Substances that dissolve in water are typically polar molecules or ionic compounds. Polar molecules have a positive and negative end, allowing them to interact with water molecules through hydrogen bonding. Ionic compounds dissociate into ions in water due to their charges being attracted to the polar water molecules.
Are non polar molecules soluble in water?
No.Water can't dissolve non-polar molecules. Water is a polar molecule. Since polar molecules can only dissolve with polar molecules, and non-polar molecules can only dissolve with non-polar molecules, water and non-polar molecules don't react together. Exception:- Some very small non-polar molecules can dissolve in water, like oxygen (O2)
If a water molecule is neutral why does it attract polar molecules?
Water molecules have a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, causing it to be a polar molecule. This polarity allows water to form hydrogen bonds with other polar molecules, such as those containing oxygen or nitrogen, leading to attraction between water and other polar molecules.
Why are organic molecules that contain oxygen atoms more soluble in water?
Organic molecules containing oxygen atoms, like alcohols and ketones, are typically polar due to the electronegativity difference between oxygen and other atoms in the molecule. This polarity allows these molecules to form hydrogen bonds with water molecules, enhancing their solubility in water.
If water has no net charge explain why it attracts polar molecules and repels non-polar molecules?
Water attracts polar molecules and repels non-polar molecules because water has polar molecules. Water does have a net dipole though it doesn't have net charge.
Are water molecules polar or unpolar?
They are polar
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.
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.
What types of substances dissolve in water?
Substances that dissolve in water are typically polar molecules or ionic compounds. Polar molecules have a positive and negative end, allowing them to interact with water molecules through hydrogen bonding. Ionic compounds dissociate into ions in water due to their charges being attracted to the polar water molecules.
Do water molecules attract nonpolar molecules such as oil?
Yes, but they attract polar molecules more strongly."Hydrophobic" molecules is a misnomer. The nonpolar molecules in question are attracted to water molecules (usually more strongly than they're attracted to each other, even), but they get "shoved out of the way" by polar "hydrophilic" molecules which are even more strongly attracted to water molecules.
Why cant salt dissolve in water?
it can, polar water molecules easily dissolve polar molecules, or ionic compounds such as salt.
Are there molecules in water?
Yes water is a polar molecule
What substance dissolves best in water?
Ionic compounds, such as table salt (sodium chloride), generally dissolve best in water due to the attraction between the ions and water molecules. Additionally, polar molecules, like sugar and alcohols, can also dissolve well in water because water is a polar solvent that can easily interact with the polar molecules.
What are some interesting facts about oil?
Water molecules won't form a solution (are not miscible) in oil. The reason is that water molecules are polar, and oil molecules are not. Water molecules, in an environment of oil, are attracted to each other, and this polar bonding excludes the oil molecules.
Is fat polar?
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Why does NaCl dissolve in water?
Water is polar. NaCl is polar. Polar substances are soluble in polar solvents.
