Non polar molecules have uniform charge distribution . How can we say?
Uniform Charge Distribution in Non-Polar Molecules
Non-polar molecules are those that have no net dipole moment. This means that the distribution of electrons in the molecule is symmetrical, resulting in uniform charge distribution.
Electronegativity
Electronegativity is a measure of an atom's ability to attract electrons towards itself in a covalent bond. In a non-polar covalent bond, the electronegativity of the two atoms is equal, resulting in a symmetrical sharing of electrons between the atoms. As a result, there is no separation of charges and no net dipole moment.
Molecular Geometry
The molecular geometry of a non-polar molecule is also symmetrical. This is because the atoms in the molecule are arranged in such a way that the dipole moments of each bond cancel out each other. For example, the carbon dioxide molecule has a linear geometry, resulting in the cancellation of dipole moments.
Example of Non-Polar Molecules
The following are some examples of non-polar molecules:
- Carbon dioxide (CO2)
- Methane (CH4)
- Ethane (C2H6)
- Tetrachloromethane (CCl4)
Conclusion
In conclusion, non-polar molecules have uniform charge distribution because of the symmetrical sharing of electrons between the atoms in the molecule and the cancellation of dipole moments due to the molecular geometry.
