Hello students.
00:02
So in this question we are given with the compounds and we have to tell the electron pair geometry and the molecular geometry.
00:09
So before going to the geometry, we should know what is the difference between the electron player geometry and the molecular geometry.
00:15
When we talk about the electron pair geometry, electron pair geometry, this electron pair geometry is the name of geometry where we consider the electrons or the groups.
00:35
Electrons or the groups are been considered on the on the central atom on central atom atom and just in the case that they are bonding or non bonding just this we decide that whether the electrons or the groups are bonding or non bonding the shape and the geometry is not given by this electron fair geometry they just tell us what whether electrons are bonding or non funding okay when we talk about the molecular geometry molecular geometry molecular geometry molecular geometry is initially given by our theory we have okay it is given by the theory it is v s e p r theory so according to this theory we decide the shape of the geometry we decide okay we decide the shape of geometry on the basis of electron pair geometry on basis of electron pair geometry this i'll write epigy on basis of epigy we decide the shape of the molecule shape of molecule all right so we have the shape of molecule according to the electron geometry so let us get started with our question so for the electron peergometry what we do is we see the number of electrons over here.
02:15
So, if you see in this compound, what, how many bonded groups are there? there are only two groups that is one over this side and one over this side.
02:23
Okay.
02:23
And there is one loan pair over here.
02:25
Okay.
02:26
So what that means is we have three number as total.
02:31
So we have one loan pair as lpn writing and two groups.
02:36
So we are having three and due to this three we have the electron pair geometry as electron pair geometry as triangular planar we have it as triangular planar all right and if the molecular geometry we talk it about it will be in the bent shape bent why because due to the lone pairs there will be repulsions to these ones okay so that is why it will be in the bent shape so now moving on to the next one we are having of we are having of sulfur and sulfur with the two chlorine right so sulfur with two chlorine again if we count down how many groups are there two groups are there right one and two and if we talk about the loan pairs okay loan pair is two over here i have just missed the one we are having two lone pairs on sulfur here okay these two lone pairs are also present all right so here you can see that what we have is we have have okay we have two loan pairs plus two groups so this will is equal to four and for four we generally have the electron pair geometry of tetrahedral we have the electron pair geometry of tetrahedral fine so now if we talk about the this molecular geometry it will be in the shape of bent shape again.
04:36
Okay, same the repulsions of the loan pair will be there.
04:40
And here next, if you see we have carbon dioxide.
04:43
In carbon dioxide, we have two groups and zero loan pair.
04:48
So we can write due to the presence of two groups, we have this geometry as electron pair geometry as in the shape of linear shape.
05:03
Okay...
