polarity... polar is the mid- range; nonpolar is the least polar.
A nonpolar covalent molecule is one where electrons are shared equally between the atoms, resulting in no overall charge difference across the molecule. An example of a nonpolar covalent molecule is molecular nitrogen (N₂) or oxygen (O₂), where the two identical atoms share electrons equally. In contrast, molecules with significant differences in electronegativity between bonded atoms tend to be polar. To identify a specific nonpolar covalent molecule from a list, look for symmetrical diatomic molecules or hydrocarbons with nonpolar bonds.
Molecules with nonpolar bonds typically consist of atoms with similar electronegativities forming covalent bonds. Examples of molecules with nonpolar bonds include O2, N2, and H2. These molecules exhibit no permanent dipole moment due to the equal sharing of electrons between atoms.
Hydrophobic interactions are exhibited between nonpolar molecules or regions of molecules. These interactions occur when nonpolar molecules are forced together in an aqueous environment, causing them to minimize contact with water by associating with each other. This drives the formation of structures like lipid bilayers in cell membranes.
Benzyl alcohol is soluble in ether because both benzyl alcohol and ether are nonpolar in nature. Like dissolves like, so nonpolar molecules tend to dissolve in other nonpolar solvents such as ether. This is due to the lack of significant difference in electronegativity between the molecules, allowing for interactions such as London dispersion forces to occur.
The intermolecular force that attracts two nonpolar molecules to each other is called London dispersion forces. These forces arise from temporary fluctuations in electron distribution within molecules, leading to the formation of instantaneous dipoles. These dipoles can induce corresponding dipoles in neighboring molecules, resulting in a weak attraction between them. Although individually weak, these forces can become significant in larger nonpolar molecules or in bulk quantities.

Nonpolar covalent molecules share electrons equally between the atoms, leading to a symmetrical distribution of charge and no net dipole moment. This results in their nonpolar nature and lack of attraction to polar molecules.

Hydrocarbons and other nonpolar molecules are not attracted to water because they are nonpolar themselves, causing them to be hydrophobic. This is due to the difference in polarity between water (a polar molecule) and nonpolar molecules, preventing them from forming hydrogen bonds and leading to low solubility in water.
Polar molecules have an uneven distribution of charge due to the presence of polar covalent bonds, leading to interactions like hydrogen bonding and higher boiling points. Nonpolar molecules have a more symmetrical distribution of charge, making them less interactive with other molecules and typically having lower boiling points.
One example of an organic compound that is not soluble in water is oil. Oil is composed of nonpolar molecules that do not interact well with water molecules, resulting in limited solubility. This lack of solubility is due to the differences in polarity between the nonpolar oil molecules and the polar water molecules.

Nonpolar substances are not attracted to the polar molecules in the solvent due to differences in their electrical charges. This results in weak intermolecular forces between the nonpolar substance and the polar solvent, making dissolution less likely. Thus, nonpolar substances tend to remain clustered together rather than dispersing in the polar solvent.
Nonpolar molecules are typically attracted to other nonpolar molecules, driven by Van der Waals forces. These forces are temporary fluctuations in electron distribution that can create weak attractions between nonpolar molecules even though they do not have permanent dipoles. This attraction is often referred to as London dispersion forces.
