The Sulfur Dioxide i beg your pardon is additionally known as Sulphur Dioxide is the reality of a bond in between Sulfur and also Oxygen atoms. It is well-known as a formula created as SO2. Right here we will provide an explanation that SO2 molecular geometry, SO2 electron geometry, SO2 bond angle, and also SO2 Lewis structure.

We recognize that the shape which minimizes the repulsions of electronics pairs is embraced by the molecule to type the structure. The molecular shape of SO2 is exact same as the molecular geometry that Carbon Dioxide (CO2). Us will display the bonding of SO2 without making assumption below.

O === S === O

Now, if we desire to examine the exact molecular form of SO2, then us should know the positions and variety of electrons distributed in between Sulphur and also Oxygen. In the outer level, Sulphur has actually six electrons, and the Oxygen has four of them among which one electron is provided for each bond. So total number of ten electron in five pairs. To do bonds, four pairs space needed, so one pair remains alone. The two twin bonds use 2 pairs each and type as a solitary unit. 

As the solitary alone pair no counted in the shape’s description, we can conclude that the molecular form of SO2 is V-Shaped or Bent. So, our an initial perception the the initial structure does not match with the original one. 


Difference the Electron Geometry Vs molecule Geometry

Though there space so many similarities in between the electron geometry and also molecular geometry, there space some key differences. Among the many notable distinctions is the the electron geometry can be linked with one or more molecular shapes. It counts on the central atom’s structure of electrons of the molecule, while the molecular geometry depends on the various other atoms also which space bonded come the main atom or the free pairs the electrons.

SO2 Electron Geometry

The electron geometry that SO2 is created in the form of a trigonal planner. The 3 pairs of bonding electrons arranged in the aircraft at the angle of 120-degree. Together the one pair stayed alone, two twin pairs are bonded and type a bend shape.

SO2 Lewis structure

To produce the Lewis structure of SO2, you need to arrange the eight valence electron on the Sulphur. To style the ideal Lewis structure, you additionally need to calculation the formal fee of every atom too. You understand that both the Sulphur and also Oxygen has six valence electron each. Right here we have actually two Oxygen atoms, so a total variety of valence electrons will be eighteen.

We will location Sulphur at the center and also Oxygens in ~ outsides. Currently we will put the pair of electrons between the atom to produce bonds.Now let’s calculate the formal charges.For Oxygen:No. Of valence electron = 6No of bond = 2Lone bag = 2So, Formal charge (FC) = No. That valence electrons – No. Of bond – 2 X (No. Of lone pairs) = 6-2-(2×2) = 0For Sulphur:No. That valance electron = 6No. Of bonds = 2Lone bag = 2So, FC = 6-2-(2×2) = 0Now, we will type the structure by completing the octet v the most electronegative aspect O. Us will ar a dual bond and a solitary lone pair v each atom the Oxygen.We will complete the framework by placing the stayed valence electron on the central atom. Here we have 4 bond pairs and also four lone pairs, so complete electrons supplied are (4+4) x 2 = 16. So, the number of remained valence electrons are 18-16 = 2. We will placed these electrons on the atom that Sulphur.So, our final Lewis structure of SO2 will certainly be like:


SO2 bond Angle

The SO2 has a bond angle of 120-degree. One solitary atom the Sulphur is bonded v two atom of Oxygen covalently. It causes a repulsion of electron bag to type the 120-degree angle.

Is SO2 Polar or Non-Polar?

By examining the Lewis structure of SO2, we can see that the SO2 is asymmetrical since it includes a an ar with different sharing. The molecular geometry of SO2 has a bent form which means the top has actually less electronegativity, and also the bottom inserted atoms of Oxygen have much more of it. So, the conclusion is, SO2 is a Polar molecule.


Here, us have explained the molecular geometry, electron geometry, Lewis structure, bond angle, and polarity the SO2 (Sulfur Dioxide). You have the right to share her thoughts for any information missed here or if you want to know more about anything. You will obtain a reply from the expert.
