A hydrogen bond
Dipole-dipole interactions are common to all polar molecules but not nonpolar molecules. This force results from the attraction between the positive end of one polar molecule and the negative end of another polar molecule.
Hydrocarbons are nonpolar molecules.
Polar bonds occur when there is an unequal sharing of electrons between atoms in a molecule, resulting in a partial positive and partial negative charge. Polar molecules have an overall uneven distribution of electron density, leading to a positive and negative end. Not all polar bonds create polar molecules, but all polar molecules contain polar bonds.
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.
No, not all compounds with polar covalent bonds are polar molecules. Whether a molecule is polar or nonpolar depends on its overall symmetry and the arrangement of its polar bonds within the molecule. In some cases, the polarities of individual bonds may cancel out, resulting in a nonpolar molecule.
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.
Hold polar molecules together
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
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.
