Is CS2 a polar molecule?
Carbon disulfide (CS2) is a nonpolar, linear molecule. Carbon forms slightly polar bonds with sulfur, but due to the symmetrical arrangement of the bonds, the polarities cancel out. Carbon disulfide is a linear molecule, with carbon at the center. Carbon forms double bonds with each of the sulfur atoms.

How to find CS2 hybridization and molecular geometry
1.Determine the number of lone pairs of electrons in the core carbon atom of the CS2 Lewis structure. Because the lone pairs of electrons on the carbon atom are mostly responsible for the CS2 molecule geometry planar, we need to calculate out how many there are on the central carbon atom of the CS2 Lewis structure.
Calculate the number of molecular hybridizations of the CS2 molecule
What is CS2 hybridization? This is a very fundamental question in the field of molecular chemistry. All the molecules are made of atoms. In chemistry, atoms are the fundamental particles. There are four different types of orbitals in chemistry. They are named s, p, d, and f orbitals.
Molecular Geometry Notation for CS2 Molecule
Determine the form of CS2 molecular geometry using VSEPR theory. The AXN technique is commonly used when the VSEPR theory is used to calculate the shape of the CS2 molecule.
Summary

Thus, in the case of CS2, Sulfur is the bonded atom.
What is CS2 in chemistry?
Carbon disulfide or CS2 is one of the very common molecules we come across while studying chemistry. If you have ever come across the formation of carbon tetrachloride, a well-known reaction while studying chlorine, you have heard about CS2. Now let us learn about this sulfide in a detailed manner.
How many valence electrons does sulfur have?
1. Carbon belongs to Group 4 of the periodic table. Therefore, the number of valence electrons in the Carbon atom =4. Sulfur (S) belonging to Group 6 has 6 valence electrons. CS2 has two S atoms, hence, the valence electrons in sulfur here are 6*2=12. Total valence electrons is CS2 = 12+4 = 16. 2.
What is Lewis structure?
Lewis Structure is one of the key terminologies to understand the chemical bonding of a molecule since it represents the molecular structure. It depends on the octet rule concept and is an extension of the electron dot diagram. Thus, to have a comprehensive idea about CS2 Lewis Structure, let us go through each step clearly and systematically.
How to draw the structure of a molecule?
The very first step towards drawing the structure of a molecule is to decipher the total number of valence electrons. (A valence electron is a name given to the outer shell electron of an atom that takes part in the creation of a chemical bond).
What is CS2 used for?
It can be used for the production of viscose rayon and cellophane.
What is the final step in Lewis diagram formation?
The final step of Lewis diagram formation is to verify whether all the atoms are in their lowest possible formal charge. (A formal charge, also abbreviated as FC is the charge that is assigned to an atom of a molecule when we assume that chemical bonds are always shared equally between atoms inside a molecule.)
