Interhalogen Compounds Video Lecture | Chemistry for JEE Main & Advanced

hello friends this video on peacock 54
is brought to you by exam fear calm no
more fear from exam since the intra
algae compounds in fact we have
discussed this and we talked about the
reaction of hell it in with other
halogen so intelligent components are
compound which has two different
halogens like two different hydrogen
they react with each other to form enter
Heaven component we have discussed as it
has of this form X X dash of X X - 3 X X
- 5 when X is 7 right 4 X X - we had so
many options CL air I CL BR I BR this is
long what X X - 3 I have CL left wing
and I have BRF 3 my CL 3 I am I or X
it's just finally the example as BRF Phi
Phi F Phi C Phi 4 X 6 - the only example
is if7 all that we discussed that in x x
- this is a bigger size and this is
smaller size this is again more
electropositive this is we have seen
that as per the naming convention the
first one is more electropositive the
second one is more electronegative
example if you see fluorine is more
electronegative than chlorine chlorine
is more electronegative bromine chlorine
is more electronegative denying bromine
is more electronegative in idea in this
operon is more like negative then I
already okay also the ratio of the radii
of my X in X - or the ratio of the
electronegativity also of X and X - or
actually the size the ratio of the radii
are actually that determines the number
of molecules
central atom can have for example
iodine and fluorine the ratio is maximum
correct take the electronegativity
radiation or the atom it's all same
because before the same thing so in this
case the ratio is maximum so you
I yourself this this is the most
electronegative this is the minimum
electronegative inheritance okay so that
way I f7 is the only cap on okay for
other examples if you want you can see
bromine and iodine i BR 3 so if you see
b RF 5 we have BR f b RF 3 b RF 5 but we
don't have b RX m okay so if you see I
see em I see L we have i CL see we don't
have I see a Phi so it all depends on
the ratio of electronegativity of these
two compound which I am talking about
more in the ratio I have more number of
bonds we talked about the preparation of
attraction component that is directly by
combination of two her vision for
example chlorine plus cooing we have
seen this reaction at 473 Kelvin here
you get CL f equal volume if you take
flowing and act as access you get CL
Utley 573 similarly chlorine will react
directly with iodine equal volume you
get CL I mean it's here I know we'll get
I CL why because chlorine is more
electronegative so I'll write the right
side again I didn't react with the
here our chlorine excess I get i CL 3
similarly I can react bromine with
fluorine here it is diluted with water
whatever you get to VR f3 same thing my
bromine with chlorine here
fluorine is an access so again the
listeners you get into having the bound
by heating to different how urgent now
again depending
which one is access and the temperature
we get different icon in 2004 talk about
the proper let's see the intro thousand
compounds we discussed about this
interhalogen compounds you prepare by a
diet combination of two halogen
compounds and you talk about the
properties of this internal in compounds
they all covalent and we discussed why
their covenant because these inter
husband abounds X and X dash both are my
halogens and both of them are not
willing to give electrons since none of
them are willing to give electron to
form a bond sharing of electron is only
possibility and sharing of electron
gives covalent bond all our covalent one
okay and they are all die magnetic okay
and they are some gas they are liquid
solid they are all steel the melting
point and boiling point is higher then
the parent halogens this higher than my
parent halogen
okay example see LNF the melting point
boiling point is higher than chlorine
and fluorine respectively the third is
they are more reactive this is pretty
interesting they are more reactive than
parent hydrogen Y because X X - bond is
weaker than X x1 or the interest exact
spot for example here CL f CL f bond is
weaker than putting chlorine bond or
fluorine putting on okay or well let's
suppose I take idea so here I be a bond
is bigger than I am a bond or br br one
alright so if you seek your properties
this CL f is colorless gas BR f is
peeled on grass
similarly doc clf3 this colorless gas
BRF 3 is a yellow-green liquid i F 3 is
yellow order i CL 3 is on solid hi-fi is
colorless gas so they are different in
combination you talk about the structure
these X X 3 is been T shape X X 5
they are all square pyramidal and this
equation is pentagonal bi-pyramidal we
have discussed this Ashley okay and if
you talk about this hydro versus let's
talk about the hydrolysis all these
undergo hydrolysis all these hydrogen's
they undergo hydrolysis and they give
halide ions they give halide ions okay
from the smaller halogen so this example
in this X dash so this particular people
will give up
halide I'm sorry
this one is smaller right things is yeah
so this one we will give a halide ion X
dash because you're smaller smaller
halogen okay and it will give one more
acid I can say hypo Hellas acid or hypo
Halleck acid it will depend hypo Halleck
sometimes he'll I ate some paper halide
and that will be from this one the
bigger one for example they give an
example exactly X dash when you react
with water this one X minus is a smaller
one here it will give what it will give
hello iron okay that is H X - you'll get
X or X this is my hypothesis
okay similarly if it is X X - 3 with
water you'll again get HX - that is for
sure but here you'll get h o 2x please
highlight if it is X X - 5 kind of thing
and again react with water it will again
get a chicks - that is for sure
+ here to give H o 3x that is helot and
X X - 7 it will react with water to form
X it's - that's h o4 x that is perfect
so we have seen this is hypo halide is
highlight this is highlight this is
perhaps also you can actually derive
using mine using the VSP our theory we
will see one example later so that's all
about the property or the sector halogen
compound this is point to be noted with
a more reactive than my parental
halogens and they all covalent bond they
have higher melting point one point and
on hydrolyzes they all and grow
hydrolyze this they give halide ions
from the smaller one give halide ions
and from the bigger one it gives
sometimes hypoa right sometimes halides
and x la its obtains per hara time okay
now let's talk about the users of this
interhalogen compounds so it is used as
non
Aquos Solomon places where we don't need
a quest and meaningless solvent we need
we sometimes use is no inter housing
upon's is non a quest solvent we also
use this as fluorinating agent
norine eating agent this is used as a
leavening agent and Atlee the CLF six
and BRF three they are used for
production of you exit uf6 in the
English mint of the Sudan you react with
CL f6
you get a wave 6 + 3 CL by this
uranium-235 a3 so it is used for the
enrichment of the nuclear fuel again see
