simple defintion of polar and non polar
Polar and nonpolar are terms used to describe the distribution of electric charge in a molecule.
Polar molecules have an unequal distribution of charge, resulting in a slight positive charge at one end and a slight negative charge at the other end. This charge separation is caused by differences in electronegativity between the atoms in the molecule.
Nonpolar molecules have an equal or nearly equal distribution of charge, resulting in no significant charge separation. This occurs when the atoms in the molecule have similar electronegativities or when the molecule is symmetrical.
Polar and nonpolar are terms used to describe the nature of chemical bonds and molecules.
In simple terms, a polar molecule is one that has an uneven distribution of electrical charge. This occurs when the atoms in the molecule have different electronegativities (ability to attract electrons). As a result, there is an unequal sharing of electrons, creating an uneven distribution of positive and negative charges within the molecule. Water (H2O) is a common example of a polar molecule.
On the other hand, a nonpolar molecule is one that has an equal distribution of electrical charge. This occurs when the atoms in the molecule have the same or similar electronegativities, resulting in an equal sharing of electrons. Nonpolar molecules are often symmetrical in shape. Examples of nonpolar molecules include oxygen (O2), nitrogen (N2), and methane (CH4).
In summary, polar molecules have an uneven distribution of charge, while nonpolar molecules have an equal distribution of charge.
