Answer = SCN- (Thiocyanate) is Polar What is polar and non-polar? Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.In order to calculate the formal charges for SCN- we'll use the equation:Formal charge = [# of valence electrons] - [nonbonding val electrons] - [bonding ele...

Drawing the Lewis Structure for SCN-

Viewing Notes:

SCN- is without doubt one of the tougher Lewis constructions to paintings with. You'll need to calculate the formal fees to come to a decision which is the best Lewis structure for SCN-. Note that both Lewis buildings show within the video have formal charges of -1. The difference is the unfavourable is at the Sulfur (S) atom in a single structure and at the Nitrogen (N) atom within the different. Because N is extra electronegative it makes extra sense for it to have the destructive rate. As a result the SCN Lewis structure with the N having a detrimental one formal price is the most productive structure. The Lewis structure for SCN- has Sixteen valence electrons.

Transcript: This is Dr. B. We're going to have a look at the SCN- Lewis structure. It's slightly extra of a difficult structure, however it does incorporate probably the most large ideas about Lewis buildings and why we draw them for a molecule. So each of the Lewis structures for SCN- which can be drawn right here, and they are resonance structures--each of those uses all of the 16 valence electrons that we began with. The formal fees for each one add up to adverse 1, and that makes sense because now we have a adverse 1 up here. Let's check out the formal charges for every single this sort of and spot what is going on on--which one's going to be the best Lewis structure for SCN-.

So let's do this one first, here. So for the Sulfur at the periodic desk, 6 valence electrons. Then we take a look at our Lewis structure. Nonbonding, there are 6 nonbonding. Then we've 2 eager about a chemical bond. We'll divide that by 2. Six minus 6 minus 1; Sulfur has a detrimental one fee. The Carbon and the Nitrogen, they both have formal fees of 0. This is smart, as a result of when you add the formal charges up, you'll be able to see that you've got a negative one charge for this molecule, and this unfavourable up right here. That makes a large number of sense.

Now let's take a look at the following Lewis structure right here for SCN-. Let's look at this one here and calculate the formal charges. So for this Lewis structure right right here for SCN-, we can see that the Sulfur and the Carbon both have formal fees of 0. The Nitrogen, on the periodic table it's in staff 5, so it has Five valence electrons. These right right here and listed below are nonbonding, so 2 plus 2 is Four nonbonding. And then we've got 2 plus 2 again; 4 bonding electrons which we divide through 2: it has a -1 fee. So at this point, we see that each buildings are just about similar. The most effective distinction is, over right here the Sulfur has a -1 charge. Over right here, it's the Nitrogen that has the -1.

So we want to come to a decision about which is going to be the in all probability molecule for the SCN- ion to exist. There's in point of fact now not a large difference between the two structures that we will be able to see here as opposed to that -1 price at the Nitrogen. That actually goes to make the variation. Nitrogen, it makes more sense for it to have a -1 rate than it does for Sulfur as a result of Nitrogen's more electronegative. Because of that, this proper here is going to be the more likely Lewis structure.

So in a sample, it's much more likely that you'll in finding this compound proper here, this resonance structure of the SCN-. however it isn't going to be a large difference. They're so identical, and we are simplest looking at an electronegativity difference here. There'll be numerous this within the sample, however the majority can be this SCN- ion proper right here.

This is a superb structure to look at and consider as it contains a large number of those big concepts like having a look at formal fees, resonance buildings, and electronegativity. So return and glance over this once more. Try to solve it for your self and make sure you perceive these ideas. This is Dr. B., and thank you for observing.
