Structural-isomerism and types - Coordination Chemistry, Inorganic Chemistry Video Lecture - IIT JAM | Best Video for IIT JAM

hello friends this video on coordination
compound part 12 is rocky by example a
calm no more fear for exam the next is
structural isomers they told they have
different wants we have same molecular
formula different bonds from different
structures in this case carbon is bonded
to nitrogen for echovirus by epoxy but
they have same molecular
then
other example for this can be h3 4br to
see this is tetramine die bromo Platinum
flute right one more three there the
bromine is the comprehending the
comprehend but if you see both case the
molecular formula is same structure for
management this is those example of
structural icicles let's study some
different type of specialization what is
the first of the linkage isomers so this
happens when the ligand has more than
one donor atom this is I immediately in
this building is up and we they they
they believe is e cobalt nickel cobalt
oxide this is red in color and this is
yellow in color okay
in fact other examples of ambient
linkages scn- so this also have this
kind of mode the metal can bond with
hydrogen little can go on with suffer so
those are examples is thiocyanate one is
signing this is also example of the
imitations
if you see this game this is one two
three four five pent I mean this is
Nitro pen I mean Nitro Chabad this is
three actually a charge card three iron
this one efficient
this is Penta mean this is my throat oh
this is my name was a differ this is
Penta to mean nitro cabal three and
suspend time in night critic avoid the
eyes that is linkage I suppose so let's
study coordination isomers so this type
of isomerism exist in the coordination
compound which is made up of cationic
and anionic conflicts this arise
actually the interchange of legend
between the Ni and I on again the
cationic entities let me give an example
of this this one understand so i co h 3
6 c CN so here you know this if I make C
RL is 3 6 6 s so now if you see here the
Khobar was bonded to a this 3 here the
cobalt is bonded to see here o here is
buoyant ocn here chromium is wanted to
finish 3 that's what that's what I told
this type of ice will exist in the
coordination component which is made of
Katanning in anionic complex and so I
have a cationic complex and I have a
highly complex and both
so in this case if I have Kittanning in
a mnemonic complex ions and if we
interchange the legend so if we
interchange the ligands between this
cationic and anionic entities of these
metals you get the stable coordination
of course the example can be cooperative
in young and back in with livers here
okay that is coordination issues
the next is ionization isomers the names
of this ionization that is my counter
ions they are involved here so the
compound which have some composition I
mean which has same composition but have
different differentiate ions in the
solution so the composition is same but
they give different ions in solution for
example that you see you in this 3y so4
this is one where is the solution you
put in there
these two complex compound if you put in
solution this will be BR minus I in this
video so four minus X right this is red
this is violet now you see is a
molecular formula same okay but it gives
different ions so this happens because a
counter ions if it's a vocation Lincoln
so here
counter is teaching so here BR is a
contra and here we are the leaving a
reservoir is a contra here
okay so here this contra in the
potential ligand and it can actually
display the ligand and then it shall
become count their scale of scenarios
another example can be a platinum with
jr. okay this is Ted time in die bromo
platinum - right this is straighter I
mean Dyke group I didn't ruin so these
are example of ionization this is
similar to ionization my so much the
only difference here is that we have
water also as part of ligand or you can
see a counter ions so here the water is
solvent water may be outside or inside
coordination sphere example see our h26
CL 3 from this only you can make see our
h2o 5 CL 2 dot h2 or you can say c rh 2
this yield on to h do this is violet
this is green is w these are example of
hydrate patients or here Cobar with
chlorine is somewhat 4 molecule here
this ammonia here this is a writer same
thing see you and she talked this we
have to see into here here I am CNN what
what what it ago so here what I wanna
get inside here whatever will also this
is also example of solvate of high grade
items they told this similar to
okay so we have to indicate the type of
isomerism and draw the structure of
these isomers kc r s2 and c2 so here if
you see the coordination number is 2
plus is by dentin 2 into 2 4 2 plus 2 or
6 correlation in verse 6 the distance of
the header now they are two water
molecules and to see 2 4 4 or the cool
straight oxalates so there are two
possibilities one possibility is this is
trans that is both the water molecules
are separated from each other and
balances it is both the water molecules
are near each other and this see two
more actually you can form this right of
the ridiculous
so in this case it is a trance
if you draw a mirror image you feel
exactly similar to this that will that
will be superimposable so in this case
no optical activity in this case is this
is sis
if you draw a mirror image actually
you'll get one optical active isomers so
this will be one will be laid over red
ribbon will be dictum okay there are
three isomers 1 2 & 3 these two are
actually symmetrical isomers these two
are optical isomers okay
the next is see you en 3 uni draw the
structure you are not bothered about
this conference yui and 3 the first
charge you see here also 2 into 3 6 14
in humorous 6th then we octahedron loli
bond is here you can hand one in this
one this one is this this is one
possibility and there is no other
possibility this is the only possibility
if you have to draw this is only
possibility you have you can't be en en
and you can't just draw these two too
far the the energy levels won't allow
this to happen now this is the only
structure we have but yeah looks like if
it draw a mirror image of this we will
get something which is non super
imposable right so if you draw away you
get something
in here see these two are
non-superimposable it is to a non super
imposable and thus you can see that they
are optically active one will be
Dijkstra one will be labor of it the
next is again you have to draw an
indicator type of isomerism for this CEO
in is 3/5 no.2 for the addition but is 5
plus 1 6 6 that is tetrahedral append
then is octahedral so now we have 5
ammonia no no no - what can we do here
we have 5 ammonia and one no.2 see let's
put no.2 somewhere let's say this is
that we have ammonia if we talk about
the geometrical isomers can we have more
co-op tickle we may have because I'm
going to take a mirror image of this
from this direction you find an
optically active component so optical I
show much to conform right not on this
component it is 3 now you take an
optical image you find monkeybone and
actually you can't superimpose them
correct in that case you will get an
optical isomer also or if you talk about
geometrical isomers you not get any
but yeah since there is a no.2 here you
know to go right so in this case you can
have linked a less reversal okay Plus
also you note here that this nu 3 2 is
here correct
so this no.3 actually can go here so
what you can get is because this is a
potential negative what do you get also
this she becomes my counter and this is
a io9 she might reverse so you get
various types of isomers instance so
let's see this game platinum with
ammonia water including CC 1 plus 2 plus
2 4 coordination number 4 that means
either in the stator item or it is
better you see that later this is
actually square planar so in this case
what you can do is platinum you can get
sis both on same side or you can get
transfer these to I so much of possible
symbols give the evidence that Co NS 3 5
CS of or else you will see is CL are I
might reverse see Zionism isomers will
give different points but it resolved
and what or in either solvent which
dissolve them
again so typically we use a barium
chloride these to easily use if I have
to find sulfate and right where we use a
g3 or something we use be easier to sew
let's dissolve all these regions we have
four reactions each for each two to four
so let's see how it looks so we have you
and is 35 okay we have CL here the same
thing
we have this way see you are in is 3/5
so for CMS a anything a light works I'll
tell you why radicals
okay so thus first to react at would be
easy entry easy this also react will be
is to enter where bacl to what happen is
you'll get BS o n 0 minus 5 so with this
will it be a cellphone and here - miles
this is my solid in this case is not
meaning in this case they'll not be me
here he knows even the at least see it
in degrees feel that before maybe cm
nothing else this is also precipitate so
you see in two cases we are getting
precipitate and that you can actually
tell that this has a sophomore this have
seen the auto ion and thus they are to
ionization fishers correct see we just
do that it has different codons the same
I am actually is inside this looks like
I'm going to do that this exists so
given these sugar boundary energy meter
Larry string since by reacting with
values are for then okay so this is the
precipitate you get grooves that you're
suffering as all triangle case right has
a contour island thank you visit exam
