Polarity makes molecules attract one another more strongly; this requires more energy to break them apart.
Hydrophilic heads on plasma membranes attract water. These heads are composed of polar molecules that interact with water molecules due to their similar polarity, allowing water to be attracted to and interact with the membrane.
No, oil is not hygroscopic. Oil does not have a tendency to absorb or attract water molecules from its surroundings like hygroscopic substances do.
Water molecules can attract other molecules through polar adhesion. This occurs because water is a polar molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other. This polarity allows water to form hydrogen bonds with other polar substances, leading to adhesion. In contrast, nonpolar molecules do not exhibit such interactions with water.
Polar molecules like sugar and water attract each other due to the presence of positive and negative charges within their structures. The positive end of one molecule can interact with the negative end of another, creating dipole-dipole interactions. This attraction allows polar substances to dissolve in one another effectively, facilitating processes like the dissolution of sugar in water. Thus, the polarity of these molecules plays a key role in their interactions and solubility.
No, the tendency of water molecules to attract each other is due to hydrogen bonding, not ionic bonding. Ionic bonding occurs between ions of opposite charges, while hydrogen bonding occurs between a hydrogen atom bonded to an electronegative atom (like oxygen) and another electronegative atom.

No, electronegativity is not the ability of an anion to attract another anion. Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself when it forms a chemical bond with another atom. It is a property of atoms, not ions.
This property is technically known as electronegativity.
No, opposite polarities attract, alike polarities repel.
No, oil is not hygroscopic. Oil does not have a tendency to absorb or attract water molecules from its surroundings like hygroscopic substances do.
Water is polar because of its unequal sharing of the electron which makes hydrogen slightly positive in charge and oxygen slightly negative in charge. When this happens, the slightly positive hydrogen atoms attract other slightly negative molecules, and thus, attracting other polar molecules. This cannot happen with nonpolar molecules because their charge is zero.
Yes. If their polarity is the opposite
Electronegativity is the tendency of an atom in a compound to attract electrons towards itself. It is a measure of an atom's ability to form bonds with other atoms by attracting shared electrons. Electronegativity values range from 0 to 4. Electronegativity increases from left to right across a period and decreases down a group on the periodic table.
True. Electronegativity is indeed defined as a measure of an atom's ability to attract and hold onto electrons in a chemical bond. It helps to predict the polarity of bonds between atoms.
Oil molecules are nonpolar, so they tend to attract each other through weak intermolecular forces called van der Waals forces. These forces are due to temporary fluctuations in electron distribution that cause a temporary dipole in one molecule, which induces a complementary temporary dipole in neighboring molecules, leading to attraction.
