click the bell icon to get latest videos from Ekeeda Hello Friemds in the previous lecture we have talked about that is how can we determine the molecular structure off for the and now we saw that clearly there is a beast on VSEPR theory we are about to get to mind that what will be the structure of all the molecule structure on that of water so let’s talk about it [Music] so now what we are going to do is we are dividing the water structure of whatever using VSEPR theory but in water as we know then water passes stuff basically oxygen is the central atom so that is the reason that we are not going to discuss about the electronic configuration of it first and then we are we can we to the ER for the bottom so talking about the oxygen oxygen is the one which has an atomic number of 8 so I have represented it here is that okay number of 8 and in the electronic inflation can be written as what has 1 s 2 s 2 and 2 P 4 so this is what we have so let us understand that we should express that is the subshells also and we have and the auto machine we are talking about the valence shell and the valence shell consists of s option lasers p subshell but s sure has only one orbital well the piece of shit consists of BC 3 orbitals that is what I would mention over here you know let us put with electrons any test case will get to do that is since we are talking about the downstream so therefore the tubular nodes that are representing the ice already there is a full a cross RB present in that is P orbitals that is 1 2 3 L let me discuss about the fourth or not so it here it is suppose P X py and suppose it is easy but it is the formation of the bond between the oxygen and hydrogen obviously we know that the hydrogen is between worlds first you form or that is the important with that of the unfading of the oxygen and again they are fighting it off oxygen that means two hedges are involved so as to form that is more in that of oxygen so now if I would say that what would be the hybrid for this one so it is very easy to understand suppose if this is the one that we have and in this case basically over the hybrid don’t discuss about the hydration of water in that case also we have got to go that is the oxidation about which is following that is sp3 hybridization and that’s the reason because of which the motor has a different shape compared with that often than I expected so let us talk about the water and in this case but before starting with the water and we know that hydrogen is the one which has one electron it sort of motion that is how we can represent the orphan and then also so this is what we have and it consists of basically one electron that is this one so basically we need BC two hydrogen molecule so I will try to do that we need two electrons or we could say we need to hydrogen and of each of which consists of one lindo and that money later on we can occupy over here and so us do it before morning when you’re with opposite spin and here also so we can put a lock we see we could get the hydrogen has for us that I’m going to talk about and that is for this one that is for formation or whatever you do so now we are talking about that is the electron pairs and since I have if I am talking about that is the 2 s orbital over here and this is the 2 s orbital off for the settlement because we are in VSEPR theory we are busy focus focusing on the central atom over here and the rest of the p orbitals are which present over here in this way so that is it but now let us fulfill the electrons and this 1 2 3 4 5 6 6 various electrons there therefore the oxygen but meanwhile when we are talking about hydrogen so I will just roughly 1 unpaired electron and that is what we feel it over here so making this to be total obviously in this case basically how many pair off in the process that I could see I could see the pair of illiterate s which has received immense injector penance which is you know to the connection s and 3 terms of P orbitals so therefore I could say that this is basically when I could say P X py and PZ are very odd so ultimately I am getting basically sp3 hybridized structure of water so if it is sp3 hybrid structure that similar to that of what we have got in b3 it is about which is basic but it is giving us pure sp3 hybrids to check without I mean like distortion in their egg so we had 1 0 9 degrees 20 minutes but what about water so what does is obviously to Road pair of electrons that you could see that is that is present on the oxidizer so that is the reason that that will have an effect on that is the shape of the automotive geometry of the motor so the expected shape is what we could get or expected geometry that is what we could get has tetrahedral but mean whenever you are talking about the expected angle so the expected angle or the bonding is that I am talking about here in this case it is before to me that is 1 0 9 degree 20 minutes so this is the expected on but is it actually the same thing when we could see that in the water one has a bonding experience no it is not let me give you an information over here also that is suppose if I draw the structure for oxygen over here so Daxing is the one which is present in the middle and since we are talking that it would be present in that of a tech tidal ship so let me tell you that it suppose the two hydrogens are over here and there will be no pair of electron above it and we knew it but since it consists of load pair of electrons and even that are responsible for basically for repulsion between the node pair at the board so obviously the both of the electrons they will be chilly missing they will repent with each other to SS they can repel the body electrons also that are because of the oxygens valence electron or a ballot boxes bond electron and that of the hydrogen bond electron so obviously here we could see that there are two lone pair of electrons as you see over here that is values of this one and under is of this one so they will have an effect on the hydrogen bond and hydrogen bond electrons and that’s how we could see that in spite of like that the previous age that is for nitrogen nitrogen has only one unpaired electron hell even that has it affected on the that has affected the bond angle of it but now it has me see to on unpaired electrons and obviously in this to be lab also have an effect on the morning so what happens is the expected it is we fought to be that is one zero nine degree and rotate minutes but because of what because of the repulsion between the note para at this border where you could see that the bond angle of water is basically found to be 1 0 4 degree 35 minute so this for the actual morning it is in 4104 degree the fabric and talking about the Jovita you’re talking about this shape that is what I’m going to talk about here so this shape is basically V shape as you could see you again so basically this is AP ship molecule but the Heron should we have got to know that is the shape or the shape of the water in space in your bit of the water is specific for twit attend and that is what it is clearing in the hibernation but when we see in the in the form of that is VSEPR theory again we can get a V shape and there and it is been present in plane and that is how we can give the geometry we can give the shape of the water molecule using VSEPR feel so it gives a very good detail about the bonding that’s also and why the bonding is getting reduced this all really sunk you might be missing any so that is what I want to talk about so thank you friends for watching this video I hope you see me very clearly here you have got to go various information about this and I hope you will share this belief red sandstone fergus’s then you get a thank you so much you
