Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
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.
http://encarta.msn.com/encyclopedia_761570078/kerosene.html This website through Encarta will explain to you the properties of Kerosene and tell you that it is insoluble. Kerosene with most other Alkanes are non polar, water is polar. Non polar molecules can only dissolve with other non polar molecules. The same for polar in that they cannot dissolve in any other but polar molecules.
Which of these molecules is polar
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.
Hold polar molecules together
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.
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
Non-polar molecules are generally more attracted to other non-polar molecules due to the similar distribution of electronic charge. This attraction is known as London dispersion forces. Polar molecules tend to interact with other polar molecules through stronger dipole-dipole interactions or hydrogen bonding.
No, hexane molecules are non-polar.
Polar molecules, like water, can conduct electricity to a lesser degree compared to ionic compounds. This is because polar molecules have uneven charge distribution, allowing them to form weak electrical interactions, known as hydrogen bonds, which can facilitate some level of conductivity. However, ionic molecules have completely separated positive and negative charges, making them better conductors of electricity compared to polar molecules.
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.
Yes, fatty acids are polar molecules.
