what is the name of the hybrid orbitals used by sulfur in scl2? This is a topic that many people are looking for. khurak.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, khurak.net would like to introduce to you Chemistry – Chemical Bonding (9 of 35) Lewis Structures – Sulfur Dichloride, SCl2. Following along are instructions in the video below:
Is our first example of how to put together lewis structure for a fairly simple simple molecule here called sulphur dye chloride. So first of all were going to a look. And see how many valence electrons.
Each atom has sulfur has 6 valence electrons thats how i write it. The electron symbol with a little sub v. That means valence electrons and chlorine has seven valence electrons.
So since theres two chlorines at one sulphur. Lets add up the total number of valence electrons. So this is times two.
So this is equal to six this is equal to 14 mo and together we have 20 valence electrons total. And so what were done with putting the lewis structure together. We want to make sure that we still have 20 valence electrons all right next.
We can see that sulfur since only has six valence electrons. It wants to have two more electrons. So it can accomplish that by grabbing two electrons or it can accomplish that by sharing two electrons so by making two bonds chlorine.
Only needing one additional valence electron could accomplish that by only making a single bond. So from our rule. We can say since sulfur has a lower electronegativity and fewer valence electrons chlorine has a high electronegativity.
We expect sulfur to be in the center and chlorine being on the sides. So we can expect that the molecule looks something like sulfur in the middle and chlorine perhaps on either side. Now we dont know yet if its going to be a linear molecule or is its going to be something else going on there we can usually you should detect that by looking at the symmetry once were done next we need to put in bonds.
Remember sulfur needs two bonds. Which means it can have a bond on each side with one chlorine. Atom and chlorine.
Only needs one bond. So it looks like this takes care of the need of having eight valence electrons. This will give sulfur two additional ones by sharing it with chlorine.
This will give each of the chlorine. One additional one so i think were in good shape. Now if we now add the remaining electrons that chlorine has so it has six remaining electrons.
One is used in the sharing making the bond that the seven one here the same on the other side. So were in pretty good shape. There with sulfur.
It used two of its electrons stupid. Six electrons to make the bonds one on each side. It has four remaining so lets put the additional four electrons in like that and that looks like that should be the lewis structure of sulfur dichloride.
Now were going to do a few tests. Do we have the octet rule. Satisfied well notice that here.
We can see that chlorine partytime will have eight valence electrons this chlorine part of the time will have eight valence electrons and this sulfur having four of its own electrons and then it can share. These two on either side would also have eight valence electrons. So it looks like the octet rule is satisfied what about the total number of electrons.
So notice that chlorine has six here this sulfur has four and this chlorine has six. So we have six plus four plus six of electrons that are not involved in bonding. Then we have these two that are involved in bonding and these two are involved in bonding.
So we have plus two and plus two and that should add up to the total number of available electrons. If it doesnt something is wrong we have to reconsider. So we have six plus four is ten 16 18.
20. 20 and 20 that number matches. So were good so we mad.
We followed the octet rule. We have the correct number of valence electrons total in our structure. It looks like this will do it that is then the valence or the lewis structure of the of the sulfur chloride molecule.
So thats how we do that there was a simple example. But again notice how we follow the rules. One by one to make sure we have the structure correct notice.
The perfect symmetry. I would assume that this would then become a linear molecule rather than a bent molecule. .
