How-do-you-do in this question. We have the ion I cl four With a 1 negative charge. And we want to know its molecular geometry and the bond bending. And then that means we're going to demand to do a lewis dot structure. So we will have the iodine as the key atom and it'south surrounded past the four chlorides. Each of these chlorides. Each of these chlorine is intelligent. And then it has so each i has vii valence electrons. Then I'yard going to get ahead and put in those seven valence electrons for each of the chlorides. Okay, iodine is besides a halogen. And so it also has seven valence electrons. I'm going to do its electrons in blue. So first of all, i electron is going to exist used for each bond to each client. Then that takes up four. Only it has seven plus nosotros have this negative charge that gives usa an extra electron. So nosotros yet accept four more electrons to put in here. And so that means that there are going to exist too long pairs. And then we have four Single bonds to the iodine. Mhm. And we have ii long pairs. Yeah. So that gives us an electron domain geometry of october federal. But two of these are lone pairs. So that means the molecular geometry when we accept an Octa he'd rel and only four of those are bonded to atoms. That gives us a molecular geometry. That is square planner. Mm hmm. And so the molecular geometry here is foursquare planer. And if I effort to, our next thing we need is our bond angle. And then if I try to sketch that out here, square planer, he's going to wait something like this. Where are lone pairs are on the top and the bottom. And so in other words, we accept four atoms bonded around the center. If we take a circle and we carve up it in 4360, divided past four, gives us 90°. Each of these bonds are each of these bond angles. Okay, the cl two I 2 cl bail bending, each one is 90 degrees. All correct, so we take a square planner with 90° bond angles. Give thanks y'all for watching. And I hope this was helpful.
