nonpolar molecule

 

Definitions from the Web

Term: Nonpolar Molecule

A nonpolar molecule refers to a type of chemical compound in which the distribution of electrons is symmetric, resulting in a balanced distribution of charges. In other words, the molecule has no positive or negative poles.

Nonpolar molecules are typically formed when the atoms participating in the chemical bond have similar electronegativities, meaning they share electrons equally. This results in no net dipole moment, making the molecule nonpolar.

Sense 1: Chemistry

In the field of chemistry, a nonpolar molecule is one in which the electronegativity difference between the bonded atoms is minimal or nonexistent. These molecules have symmetrical distribution of charges and exhibit no dipole moment.

Example: Water (H2O) is a polar molecule due to the unequal sharing of electrons, while carbon dioxide (CO2) is a nonpolar molecule.

Sense 2: Biology

Nonpolar molecules are also significant in biology, particularly in the context of cell membranes. Certain molecules, such as lipids, are nonpolar and play a crucial role in forming the hydrophobic (nonpolar) regions of cell membranes.

Example: Phospholipids, which are nonpolar molecules, are the main components of cell membranes.
