Which type of bond is present in hydrogen sulfide (H 2 S)? The table of electronegativities is given.

Hey everyone. So here it says classify the bonds in the substances below as ionic, non polar covalin or polar covalin. Alright, so let's first, let's define what we mean by ionic, non polar covalin and polar Covalin using our electro negative values. Now, when we're saying that something is ionic, That means that the difference in electro negativity has to be greater than 1.7. When we're saying non polar covalin, That could technically be between zero 2.4 Difference and electro negativity. And then when we're saying polar covalin, well that's just .52.7 in terms of difference in electro negativity. So here if we take a look at each of these options, let's start out with I two and I two, all we have is two, iodine is connected to one another. Since they're both the same exact element, they're going to share electrons equally. They have the same electro negative value. Their difference in electron activity is just zero. So this first one will be non polar covalin. Okay, so I'll just abbreviate that as NPC. For the next one we have sulfur dioxide. So we have a sulfur connected to oxygen. So if we look we have sulfur connected to oxygen, Sulfur has an electro negative value of 2.5, oxygen has an electro negative value of 3.5. So the difference between them is one point out And since it falls between .5 and 1.7, that means that this would be a polar covalin bond, which we abbreviate as pc. Next we have K. F. And in terms of space, let's write this stuff down here, K. F. So potassium has an electro negative chlorine is the most electro negative element with 4.0 so the difference between them is four point oh minus 4.0.8. So 3.2. So that would mean that K. F. Is an ionic bond that exists between potassium and flooring. For D. We have nitrogen di sulfide, nitrogen has an electro negative value of 3.0 Sulfur has an electro negative value of 2.5. The difference between them 3.0 -2.5 equals .5. So here this would be polar covalin. Let's look at e it's just the same elements all connected together. All sulfur is they all have the same electro negative values. So the difference between them is zero. So this would be non polar covalin. And then finally f. We have boron, tri chloride, boron has an electro negative value of two point Oh, Chlorine here has an electro negative value of 3.0 the difference between them Is 1.0 so that would mean that this possesses a polar covenant bond. You just read the whole thing since we're at the end. So that's how we classify each of the bonds found within each of these compounds
