a. $\mathrm{SCl}_{2}$
b. $\mathrm{PI}_{3}$
c. $\mathrm{Cl}_{2} \mathrm{O}$
d. $\mathrm{NH}_{2} \mathrm{Cl}$
e. $\mathrm{SiCl}_{3} \mathrm{Br}$

Explanation for the question. Here we have a number of molecules. We have to find the liver structure and molecular geometry and the nature of polar and non polar property. So here the molecule is s I C l four. So let me see Structure for this molecule Is levy situation for this molecule is here? Yes. I easily con te Dracula, Right? Chlorine, chlorine, chlorine in chlorine And the molecular geometry for the given molecule is we have tetrahedron and next property is polar and non polar nature. So this molecule is non polar and next to behalf The molecule is s e is to so the lady structure for this molecule is here. We have s e selenium and hydrogen molecules in mercury is banned. And this molecule is polar in nature. And next we have the molecule is C is too. Oh Levy, situated for this molecule, is see the bill one all a Trojan e introgen and the molecular geometry for this molecule is try Gagner, Planner. And next we have this molecule is polar

Starting with party will draw the lewiS structures. So there's a central phosphorus Bonded to three florins and phosphorus can expand or it can have a long pair of electrons to complete the octet. And this gives an electron geometry that is tetra federal. Since there's four electron domains in a molecular geometry or the shape that is tribunal pyramidal for part B. There's C. H three plus. So that is central carbon Wanted to three hydrogen and the positive one charges on the carbon. Since there's three electron domains and no lump pairs of electrons, the electron geometry is going to be the same as the molecular geometry and that is traditional planner For part c. of BRF three. Central bro mean bonded to three Florian molecules And it has two lone pairs of electrons. The electron geometry is tribunal by pyramidal since there's five electron domains and the molecular geometry is T shaped for part D. There's c L 04 minus. So central chlorine has three oxygen double bonds and one oxygen single bond. Yeah, the electron geometry is the same as the molecular geometry since there's no lone pairs of electrons on the chlorine And that is Tetra Federal. Since there's four electron domains. Party or ex BF two CN on is the central atom Wanted to to Florian's and has three lone pairs of electrons. This has an electron geometry that is tribunal by pure middle since there's five electron domains and a molecular geometry or a shape that is linear. Lastly in part F, there's bureau to minus central grooming. I wanted to to oxygen's one is a uh oxygen double bond And there's two lone pairs of electrons on the brain. The electron geometry is tetra hydro since there's four electron domains and the molecular geometry is bent.

Explanation for the question here we will draw levy structure please please. And product mall killers were free of the flowing. So here behalf and but I. F. Five. Bye Dean paint a floor. Right. So here the levee structure for this molecule is I mean Irene is the central atom. And we have salary. Yeah. Hillary Loreen flooring and flooring florian having seven valencia and six here three long years. And when you know bounded for and here will be the same. Okay. So if mall healers you metro is molecule is your military Is molecule a unitary easier secure, tyrannical and next is part to be we have fighting try all right. And it's levy structure is Yeah. Heidi is a halogen having valence electron seven when in the shared in three long piers and you and its molecular geometry is leadership. Believe me it is showing me a tree. And next week we have in part C we have forced first painter chlorate Islamist structure is here level structure of 1st 1st paint accurate valence electrons and its molecular geometry is try Conan by pira. Middle trade corner. Bye by Roy. Yeah he does molecule is geometry. And next piece we have party selenium to a traveler, right? Islamic structure is selenium. The traveler it the traveler. Right in your small colors. Geometries. See so. And next piece we have. Yeah, but if colour etcetera flow rate is level structure is easier flooring. Mhm. And if small killers Yuma trio B T shaped.

So for this problem here we have five molecules and they want to draw lewis structures for each and then find the molecular shape from the lewis structures. And so first B H two here we know that H one, B H R and B S. Four. So total there's six and be central atom here there's four electrons right now. Plus to the long period goes on the And from this we can see that this molecule is gonna be Something like this with the lone pair pushing down the two bonds. So it should be an angular event. Next we have our CH two cl two. Mhm. So U. S. C. Carbon is gonna be connected to these two hydrants here. There's 20 electrons total. The other side's connected to the to Korine's mm And according to us we having long periods on them. And so this molecule will be shaped something like this with four bonds on the central atom. and with you draw more accurate 3D representation will be like this which is Petra. He drove. Yeah. Next we have our p three And we know that be boron has five feelings electrons. Asia's three. So there's eight. So it will be something like this with Florence pair of electrons on the boron. And because of this lone pair, our molecule will be shaped like this with the three bones being pushed down by this long hair. And so this will be a tribunal. Here are new. Next you have SECL six Oh Mhm. And we know that since Cellini um has six valence electrons. Flooring has 7- 42 total. And because of the sticks fans national Cellini um they can have an expanded octet with six chorines being attached to it. Okay if we put three on all these korans. Yeah It will complete all their outfits and 48 electrons. And this molecule will be looking at something like this, the two vertical bonds plus four equatorial bonds. And so this will be a hot to heed row. Okay. Okay. Lastly We had RPF three. Yeah, I know that phosphorus has five Bills last month The three floor is at 21. So 26 total. And the fraudsters is going to be our central atom here, 24 electrons with the flooring. So the extra two goes on the phosphorus and once again like This BH three before is going to be something like days. So I take a little pyramidal
