Polar. Just think of this, oil is non polar, oil doesnt mix with water.
Polar.
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
Because water is polar, so when a when a polar solute is put in it will dissolve. Like dissolves like. Polar dissolves polar. Likewise, nonpolar dissoves nonpolar.
Water and oil doesn't mix because the water is a polar molecule and oil is a non-polar molecule. There will always be more molecules of water than oil.
No, they are not. Micelles are formed by amphipathic molecules, that is molecules having both poplar and nonpolar regions, such as phospholipids or fatty acids. The polar region stays to the outside of the sphere as it can interact with water or some other polar solvent and the nonpolar regions are forced to the center.
A polar molecule
Water does not interact well with nonpolar substances because they do not have large enough dipoles to cause water to interact with them and not other water molecules. Water is said to squeeze nonpolar molecules together because of the hydrophobic effect it of nonpolar compounds.
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
Phospholipids do not interact with water, because water is polar and lipids are nonpolar.
Polar Molecules
Because water is polar, so when a when a polar solute is put in it will dissolve. Like dissolves like. Polar dissolves polar. Likewise, nonpolar dissoves 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.
nonpolar. The fat molecules in peanut butter are nonpolar, that is why peanut butter doesn't evenly mix with water, a polar substance.
No. Water has polar molecules so only polar molecules will dissolve in water. Nonpolar molecules will only dissolve in nonpolar solvents. For example, lipids will dissolve in ethanol.
No, sugars are polar molecules considering that they will interact and dissolve in water (which is also a polar molecule). Polar molecules will only interact with other polar molecules and vice-versa.
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
