Which has a dipole moment so2

The polarity of a molecule is decided based on the unequal charge distribution of the atoms involved in the molecule. The unequal charge distribution results in the net dipole moment. The molecule which has a non-zero value of net dipole moment is polar whereas the molecule which has net dipole moment equals zero is non-polar. The CO2, O2 is an example of non-polar molecules. You can read out the article for the reason of the non-polarity of CO2.

The molecules that have zero net dipole moment is due to equal charge distribution on the atoms in the molecule. Therefore, the dipole moment gets canceled out and results in a net-zero dipole moment. It is better to understand that the difference in electronegativity is one of the main factors that affects polarity. The polarity of a molecule is directly proportional to the difference between the electronegativities of the atoms involved in the molecule.

In the world of chemistry, electronegativity is a measure of how strongly an atom can attract an electron towards itself. More electronegative atom can strongly attract electron and low electronegative atom can weakly attract the electron.

The SO2 molecule forms the shape of the trigonal planar. The lone pair repulsion among the Oxygen and Sulfur forms a bent shape and the angle between the bonds is found to be around degrees. For more detailed information regarding geometry, hybridization, and lewis structure of SO2, you should also refer to the article on the lewis structure of SO2.

We all should understand that when two atoms form a bond, they basically share electrons from each other. And also, it is important to keep in mind that two different atoms do not equally share the electron of each other.

It is because of the electronegativity difference. The atom with more electronegativity attracts the pair of bonded electrons toward itself as compared to the atom of lesser electronegativity.

As per the studies already done, the bond formed between two atoms is polar covalent if the electronegativity difference lies between 0.

In this bond, the center of negative charge does not lie in the center. It would be at the end of an atom with greater electronegativity. And if the electronegativity difference is lesser than 0. Whereas, if the electronegativity difference is above 2, the bond is ionic.

For example, in the case of SO2, Oxygen has a higher electronegativity than Sulfur and it makes it polar. The electronegativity of Sulfur is 2. And in the case of NaCl, the Chlorine atom has a higher electronegativity than Sodium, due to which the Chlorine atom pulls the electron shared pair towards itself. If you are a student of science, it is very helpful to remember that as you move right in the periodic table of chemistry, the electronegativity of elements gets higher.

You should note down the value of electronegativity of atoms involved in the molecule, the number of lone pairs and bonds. And the overall geometrical shape of the molecule. This information is sufficient to conclude whether the molecule is polar or non-polar.

In this article, I tried to cover the polarity of sulfur dioxide, and the factors that affect the polarity, how to check the polarity of a molecule with the information required to conclude.

I hope, I cleared your all doubts regarding the polarity of SO2 and also made you understand the fundamentals of the polar and non-polar bonds.

CO2 has none, but still is pretty polar. Add a comment. Active Oldest Votes. Improve this answer. Featured on Meta. Now live: A fully responsive profile.
