the basic difference between polar and non-polar is that in polar bonds elements have different electronegativity, the electron cloud is distorted, and charges build up at their poles while in non-polar bonds, elements have the same electronegativity, the electron cloud is not distorted and does not have charge build-up. The arrangement of atoms in a molecule helps determine its polarity. A molecule is called polar if it has a positive and negative charge. A non-polar molecule is a molecule with a lower charge.

|movement||polar substances have electric dipole movement.||non-polar substances do not have dipole movement.|
|Charge separation||charge separation is present.||charge separation is absent.|
|interaction:||they can interact with other polar substances only. |
|they do not interact with other polar substances.|
|examples:||Alcohol, Water, and sulfur are common examples of Polar||Oil is a common example of Non-polar|
chemistry has lots of funs and excitement during experiments. it also has some boring terminologies like chemical properties, bonds, remembring table of elements. these concepts are a little boring and frustrating for newbies students in chemistry. the term polarity is a separation between electrical charges or chemical groups having electrical dipole moment.
in other words, polarity is the value due to the differences in electronegativity of an atom. during this, the Polar molecules interact with the help of intermolecular and hydrogen bonds. the molecularity varies on the differences in electronegativity in the different atoms of the molecule.
it also determines the physical properties like solubility, boiling, and melting points and surface tension, etc. the polarity gives us a clear dimension of an atom that how they attract different electrons to the bound molecules.
in this process, the charge values on these bonds are determined with the help of Pauling’s scale. more the greater the difference in charge from 1.7 leads the bond into ionic characteristic. if the charge value does not exceed form 1.7 the bond will be polar. if the polarity increased from 1.7 the process of polarity will be reversed.
These differences can be either higher or lower. The bond is an electron pair that is stretched more by the other atom compared to the pre-existing atom that creates the bond. This leads to an uneven distribution of electrons between the two atoms.
Due to the uneven distribution of electrons, one atom will have a small negative charge, while the other atom will have a small positive charge. Atoms now have partial negative or positive charges. An atom with a higher electronegativity gets a slightly negative charge, and an atom with a lower electronegativity gets a slightly positive charge.
Polarity means separation of charges. These molecules have a dipole moment. The dipole moment measures the polarity of a bond. Polar substances interact with other polar elements.
A non-polar molecule does not have a sufficient charge. Non-polar molecules are distributed according to the type of symmetry and do not have a large number of electric charges on them. When two atoms or two identical atoms have the same electronic bond between them, the atoms pull the electron pair.
This attraction helps them share electrons, and this kind of bond between molecules is known as non-polar covalent bonds.
