Apolaariset

Apolaariset refers to molecules that have no net electrical dipole moment. This occurs when the individual bond dipoles within a molecule either cancel each other out due to symmetry or when the bonds themselves are nonpolar. Nonpolar bonds are formed between atoms with similar electronegativities, meaning they share electrons relatively equally. Common examples of nonpolar bonds include those between identical atoms, such as in O2 or Cl2, or between carbon and hydrogen atoms, as found in many organic compounds like methane (CH4).

A molecule is considered apolaarinen if its overall electron distribution is symmetrical. For instance, carbon dioxide (CO2) has polar C=O bonds, but the molecule is linear, and the two bond dipoles point in opposite directions, thus canceling each other out, making the molecule apolaarinen. Similarly, symmetrical molecules like methane (CH4), carbon tetrachloride (CCl4), and benzene (C6H6) are apolaarisia despite containing polar bonds in some cases. The lack of a significant dipole moment influences the physical properties of apolaarinen substances, such as their solubility in different solvents and their boiling points. Apolarinen substances tend to dissolve well in other apolaarinen solvents and poorly in polar solvents like water.
