The CS2 molecular geometry is a diagram that illustrates the number of valence electrons and bond electron pairs in the CS2 molecule in a specific geometric manner. The geometry of the CS2 molecule can then be predicted using the Valence Shell Electron Pair Repulsion Theory VSEPR Theory and molecular hybridization theory, which states that molecules will choose the CS2 geometrical shape in which the electrons have from one another in the specific molecular structure.
Finally, you must add their bond polarities characteristics to compute the strength of the two C-S double bonds dipole moment properties of the CS2 molecular geometry. The molecule of carbon disulfide with linear shape CS2 molecular geometry is tilted at degree bond angle of S-C-S. But bond polarity of C-S is canceled to each other in the linear geometry. As a result, it has a zero permanent dipole moment in its molecular structure. The CS2 molecule has a nonzero dipole moment due to an equal charge distribution of negative and positive charges in the linear geometry.
Because the center atom, carbon, has two C-S double bonds with the two sulfur atoms surrounding it. The CS2 molecule has a linear geometry shape because it contains two sulfur atoms in the linear form and two corners with no lone pairs of electrons on central carbon atom. There are two C-S double bonds at the CS2 molecular geometry. After linking the two sulfur atoms and no lone pairs of electrons on the carbon atom in the linear form, it maintains the linear-shaped structure. In the CS2 molecular geometry, the C-S double bonds have stayed in the two terminals and no lone pairs of electrons on the carbon atom of the linear molecule.
The central carbon atom of CS2 has no lone pairs of electrons, resulting in linear CS2 electron geometry. However, the molecular geometry of CS2 looks linear-shaped and has no lone pairs of electrons on the carbon of the CS2 geometry.
As a result, the CS2 molecule is nonpolar. 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. This gives a total of four connections. Finding lone pair of electrons for the terminal sulfur atom is not similar to the central carbon atom.
We use the following formula as given below. For instance of CS2, their terminal atoms, sulfur, have six electrons in their outermost valence shell, one C-S double bond connection.
This gives a total of two C-S double bond connections. But we are considering only one connection for the calculation. The lone pair of electrons in the sulfur atom of the CS2 molecule is four. Two sulfur atoms are connected with the central carbon atom. In the CS2 electron geometry structure, the lone pairs on the central carbon atom are zero, lone pairs of electrons in the sulfur atom have two pairs 4 electrons.
Two sulfur atoms have two lone pairs of electrons. It means there are two lone pairs of electrons in the core carbon atom. No lone pair of electrons on the central carbon atom is responsible for the linear nature of CS2 molecular geometry.
These orbitals then combine, creating the hybrid of sp orbitals. This hybridization is known as sp hybridization. These two hybrid orbitals form sigma bonds with Carbon. Remaining eight valence electrons are taken up by the two unused orbitals of p. These electrons form the pi bonds with sulfur and are shown as the lone pairs on the sulfur atoms.
The steric number is the sum of the number of atoms bonded on the central atom and the number of lone pairs of electrons attached to the central atom. The formula to find the steric number for any molecule is:. Here in the CS2 molecule, the number of sigma bonds on the central atom is two, and there are no lone pairs on the central atom as its octet is complete by sharing the valence electrons.
Steric Number of CS2 is 2; thus its hybridization has two hybrid orbitals making it an sp hybridization. As the hybridization of CS2 is sp hybridization, the Carbon atom is in center bonding with two sulfur atoms forms the bond angle of degrees, making the molecular geometry of CS2 molecule linear.
The general formula for linear geometry is AX2, and thus CS2 shows linear geometry. The polarity of the CS2 molecule depends on the geometry of the molecule. The less electronegative Carbon atom is in the center whereas Sulfur molecule has slightly more electronegativity comparatively. 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. Carbon disulfide CS2 is a flammable, and highly odorous not tolerable molecule in liquid form. From liver and kidney diseases to weight loss and vision impairment, exposure to CS2 is not desirable.
Used as a solvent for iodine and phosphorus, it has a boiling point of Now let us move below to deeply study the concepts like lewis structure, molecular geometry, hybridization of the CS2 molecule. Lewis Structure is one of the key terminologies to understand the chemical bonding of a molecule since it represents the molecular structure. Thus, to have a comprehensive idea about CS2 Lewis Structure, let us go through each step clearly and systematically.
Step 1: 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.
Usually, the one with the highest valence i. We can determine the electronegativity value by browsing through the periodic table. As per the trend, it is likely to decrease down a group. Step 3: Now, we need to draw a skeleton diagram having the presence of single bonds. Step 4: Next, our task is to complete the octet of the atoms around each of the outer ones with the remaining electrons.
The advisable decision is to finish the electronegative ones first before starting with the electropositive atoms. Step 5: In this step, we have to check whether there are bonds left to be formed. If there is a requirement of multiple bond formation, we have to create double or triple bonds as per requirements to fulfill the octet rule. Step 6: 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.
According to Step 2, carbon is the least electronegative having the highest bonding sites. C is the central atom here. We can check and find out that both the sulfur atoms have fulfilled their octet rule here. But, carbon is the only one left with only four electrons surrounding it. We can easily mend this issue by sharing the electrons around sulfur and bringing them alongside carbon, thus 2 valence electrons from each sulfur atom towards carbon will solve the problem here.
Now, what is hybridization?
