Question

What is Polar and Nonpolar?

Answer 1

1. Polar molecules contain polar bonds due to the difference in electronegativity of two atoms that are bonded.
2. There is some charge generated in polar species, one carries a negative charge and another one carries a positive charge.
3. An electronegative atom contains a negative charge and an Electropositive atom contains a positive charge.
4. Example of polar molecules is Hydrochloric acid$\left(\mathrm{HCl}\right)$, Sulphur dioxide$\left({\mathrm{SO}}_2\right)$etc.
5. Nonpolar molecules do not have any charge or charge distributed equally in a molecule.
6. There is very less difference in electronegativity between two atoms of nonpolar molecules.
7. Non-polar molecules dissolve in nonpolar solvents.
8. Linear molecules are nonpolar.
9. Example of nonpolar molecules is Homo diatomic molecules like Hydrogen$\left({\mathrm{H}}_2\right)$, Oxygen$\left({\mathrm{O}}_2\right)$, Carbon tetrachloride$\left({\mathrm{CCl}}_4\right)$etc.
