Polar molecules have unequal distribution of electrons. Water for example, oxygen is more electronegative than hydrogen so it will pull electrons towards itself, giving oxygen partial negative charge on it and partial positive charge on the hydrogen. A hydrogen bond forms between the partial negative charge on oxygen on another water molecule and partial positive charge on hydrogen on other water molecule.
Polar molecules are attracted to other polar molecules with an opposite charge.
the other one
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.
Cyclohexanone and benzophenone are both non-polar. Water is polar. "Like dissolves like" so non-polar substances dissovle other non-polar substances and polar substances dissolve other polar substances.
Water is hydrophilic, meaning it is attracted to and interacts well with other substances, such as other water molecules or polar molecules.
Water is a polar substance, which means that any other polar substances will dissolve in it. The opposite is mineral turpentine which is non-polar so all non-polar substances dissolve in it.
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
Pepsin is a polar molecule due to the presence of polar peptide bonds in its structure. This allows it to interact with water molecules and other polar substances in its environment.
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.
Oh, dude, it's like this: "like dissolves like" is just a fancy way of saying that polar substances mix well with other polar substances, and nonpolar substances mix well with other nonpolar substances. It's basically like how introverts hang out with introverts and extroverts hang out with extroverts. So, if you want your substances to get along and mix nicely, just remember: like attracts like!
Polar substances dissolve in water because they have similar polar characteristics that allow them to interact and mix well. Non-polar substances, on the other hand, do not dissolve in water because water is a polar molecule and cannot effectively interact with non-polar molecules.
Nonpolar substances have lower melting and boiling points than polar substances because their particles are not attracted to each other like polar molecules are. They tend to be gases at room temperature (CO2, CH4, O2, etc). Not much heat is reguired to separate non-polar molecules from one another
