Polar molecules happen when there is an unequal sharing of electrons in a covalent bond. This leads to a partial positive change on one molecule and a partial negative charge on the other. An example of this is water (H2O). The hydrogens have partial positive charges and the oxygen has a partial negative charge.
Because nonpolar molecules do not have positive and negative ends
Polar are funny and Ionic aren't
Polar Molecules
quite simply: polar. Polar mixes well with polar. Nonpolar mixes well with nonpolar.
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
No, because water is polar and CH20 is nonpolar. Polar and nonpolar substances don't mix.
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.
Polar Molecules
Polar. Just think of this, oil is non polar, oil doesnt mix with water.
nonpolar. The fat molecules in peanut butter are nonpolar, that is why peanut butter doesn't evenly mix with water, a polar substance.
quite simply: polar. Polar mixes well with polar. Nonpolar mixes well with nonpolar.
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
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, in the case of polar and nonpolar the two do not mix it's like putting olive oil in milk
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
Water molecules are polar, which means the oxygen side of the molecule is more negative, and the hydrogen side is more positive. Lipids are non polar, which means that one side is not more negative than the other. This is why no nonpolar substances dissolve in polar liquids
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.
The molecule that makes up soap or detergent has a polar head and a nonpolar tail. In chemistry, compounds that are polar like to mix with other polar compounds and compounds that are nonpolar like to mix with other nonpolar compounds. This is why oil and water don't mix. Water is polar and oil is nonpolar. Oil and grease are a nonpolar compounds. When in water the soap molecules will arrange themselves in such a way that the nonpolar tails surround the grease creating a spherical droplet. On the face of this sphere is the polar heads of the soap molecule. This allows it to interact with the polar water. This is how soap and laundry detergent are able to remove oil and grease and wash it down the drain.
Molecules that do not dissolve in other molecules that are similar. If the molecules are not similar, they will not mix. Therefore, you have an immiscible liquid. Polar solvents will only dissolve polar compounds. (e.g. NaCl in H2O soln) Nonpolar solvents will only dissolve nonpolar compunds. (e.g Vitamin A in an oil) However, certain solvents are miscible with both polar and nonpolar solvents. An example of this would be ethanol (CH3CH2OH), which is miscible with water(polar) and hexane(nonpolar).
