So2 Polar Or Nonpolar
Why is SO2 polar and CS2 non-polar? 3
I have a test on Monday and I don't understand.
SO2 is a double molecule. It has two resonant structures with double bonds and single bonds and single pairs in solar. The fact that it is oblique and disproportionate makes it polar. The oxygen atom has a slightly negative charge and the sulfur atom has a slightly positive charge.
CS2 is linear, symmetrical and non-polar.
======== Tracking =========
The SO2 molecule is tilted 120 degrees due to SP2 hybridization. It can be said that the SO2 molecule has two resonant structures with a skeletal structure:
O = OS OS = O
In fact, SO bonds are identical and between single bonds and double bonds (order of bonds 1.5). This is because there is a non-hybridized portal on the S that overlaps a similar non-hybridized portal on each of the other oxygen atoms, forming a delicate p-bond. S contains a pair of electrons which then represents sp2 hybridization and consequently polar and folded molecular structures.
Danny, on the other hand, has a small flaw that leads to misconceptions. He said that there were two lonely couples in Solar. it's wrong. It will require 20 electrons, and SO2 has only 18 valence electrons that propagate through the molecule. The claim that Sulr has sp3 hybridization is also false. It is sp2 and bends 120 degrees instead of 109.5.
Danny also suggested that there are two double bonds between S and O. Formal charges are good for determining molecular structures, but are not very useful for determining bonds within molecules.
Danny finally managed to verify the link.
As a result, SO2 molecules are exchanged for only one solar pair instead of two.
CS2 is non-polar because the bonds are the same double bond between each Sulr and the central carbon.
SO bond is 1, which gives it a polar bond. Polar bonding means that there is a slight imbalance in the density of electrons. Oxygen has a slightly negative charge and sulfur has a slightly positive charge. This is because the electronegativity of oxygen attracts the electron density of sulfur. This means that SO forms a polar harmony bond. Polarity alone does not determine whether a molecule is polar. Next, we need to look at the Lewis structure of SO2. Sulr has 2 double bonds between oxygen, Sulr has 2 isolated pairs. Since there is a Sulr 4 electron density pair, it is a sp3 hybrid. Lonely couples are more invasive than bonding couples, so lonely couples cause the shape to bend. Knowing that the shape of the molecule and the polarity of the molecules are not the same, the molecule is polar (or has a liquid dupole moment).
Cs2 is polar or non-polar.
