Interhalogen Compounds | Explained by IITian | Jee Mains, Advance, NEET, BITSAT & AIIMS

Hello Guys, Interhalogen compounds are one the most important topic for Jee Mains, advance, NEET, BITSAT, and AIIMS. Generally, Passage-based questions are asked in the examination. Let's Start the topic:-
The halogens react with each other to form interhalogen compounds. The general formula of most interhalogen compounds is XYn, where n = 1, 3, 5 or 7, and X is the less electronegative of the two halogens. The compounds which are formed by the union of two different halogens are called inter halogen compounds. There are never more than two types of halogen atoms in an interhalogen molecule. There are of four general types:
AX- type : ClF, BrF, BrCl, ICl, IBr,
AX3-type: ClF3, BrF3, (ICl3)2,
AX5-type: ClF5, BrF5, IF5,
AX7-type: IF7.
Interhalogen are all prone to hydrolysis and ionize to give rise to polyatomic ions. The inter halogens are generally more reactive than halogens except F. This is because A-X bonds in interhalogens are weaker than the X-X bonds in dihalogen molecules. Reaction of inter halogens are similar to halogens. Hydrolysis of interhalogen compounds give halogen acid and oxy-acid.
NOMENCLATURE
To name an Interhalogen compound, the less electronegative element is placed on to the left in formulae and naming is done straight forward.
Properties
Some properties of interhalogen compounds are listed below. They are all prepared by direct combination of the elements although since in some cases more than one product is possible the conditions may vary by altering the temperature and relative proportions. For example under the same conditions difluorine reacts with dichlorine to give ClF with dibromine to give BrF3 but with diiodine to give IF5.
Structures
The structures found for the various interhalogens conform to what would be expected based on the VSEPR model. For XY3 the shape can be described as T-shaped with 2 lone pairs sitting in equatorial positions of a trigonal bipyramid. For XY5 the shape is a square pyramid with the unpaired electrons sitting in an axial position of an octahedral and XY7 is a pentagonal bipyramid.
ClF3 IS HYPERGOLIC
Hypergolic means explode on contact with no need for any activator. One observer made the following comment about ClF3 :
It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic* with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes."
It is believed that prior to and during World War II, ClF3 code named N-stoff ("substance N") was being stockpiled in Germany for use as a potential incendiary weapon and poison gas. The plant was captured by the Russians in 1944, but there is no evidence that the gas was actually ever used during the war.
Summary
All Interhalogens are volatile at room temperature. All are polar due to difference in their electronegativity. These are usually covalent liquids or gases due to small electronegativity difference among them. Some compounds partially ionize in solution.
Interhalogen compounds are more reactive than normal halogens except fluorine.

MKA sir, what you have taught me through your videos has totally changed how I see inorganic chemistry. Thank you so much for making me love this subject again.

[@ravikishor2640]

Flourine is too small to be a central atom,
Iodine is too big to be as a substituent.
Therefore,
Central atoms:- Cl,Br,I
Substituents:-F,Cl,Br only.
Helpful?

Sir, the colour of iodine mono chloride is brownish red. If I am wrong please notice me? the colour of iodine trichloride is lemon yelow. MY KIND REQUEST PLZZ REPLY!!!!

[@anandrevgade9377]

Sir, there is a doubt. In thermal stability lecture you said that higher the polarization, lower is the thermal stability... And in inter halogen you told T. S. order as IF) ICl) IBr. How this can be explained.. Plz reply.

[@sudhaupadhyay3537]

Awesome sir..... please continue this series

[@Trapster-vy7br]

Sir can you bring a lecture of remembering the name of Acids of sulphur and phosphorous.Very Confused between hypo,pyro,sulphuric,sulphuruos,metaphosphorous etc.Sir please Help

Sir very nice teaching no doubt....
But sir the COLOURS of the compounds as mentioned in the NCERT are different from those you told ICl is ruby red or brown red not what you told
Please sir do notice and reply
By the way, AWESOME LECTURE 👍👍👍👏👏

[@shaukatsayed6668]

Sir you said lower members are generally colourless and higher are coloured. But if you check NCERT , XX5 and XX7 are given as colourless gases/liquids. Pls explain why ?

[@akshatsachan9241]

For IF5 , why the structure Is square pyramidal? If we apply Bent's rule, lone pair should be equatorial. If we apply modified Bent's Rule the lone pair should still be in equatorial position as 90 degree angles are available at both places. Please help Sir!!

[@kartikmandhan6990]

Colour of ICl is ruby red not lemon yellow ...... Please make correction about it....

[@shaukatsayed6668]

And you said IF is very unstable and hence it shows disproportion reaction. But while explaining thermal stability, you said IF is the most thermally stable. Can you pls reply how ? If a compound is highly unstable how can it be thermally stable at the same time ??

[@earthyWZM]

Sir ur teaching level is of nexxt levelll 🔥🔥🔥🔥

Sir please upload group 17 and 18 and super detail
Plzzzz

[@bhaskarjyotiroy5633]

i have an question..sir..
higher the electronegativity difference i.e more polar and hence greater thermal stability ..
if a compound is highly stable that means less reactive.
why in case of I-Cl it is more reactive than I2 or cl2 ?

[@UDDUWALLAH]

THIS video is very beneficial to me specially..... thanks for this video

[@sowmyag5142]

Do we have to remember the uses of compounds in inorganic chemistry for jee advanced?

[@riyamamania804]

Aapki mehnat k liye hats off sir👏👏

[@daily_life317]

Very very interesting sir jii.
Nicely explanation 🙏🙏

[@KaranDoshicool]

Why Interhalogen compounds are more reactive than halogens?
Infact u told that ICl has dipole moment and hence exists as solid in comparison with br2.

[@yashgoel3402]

this channel is awesome. Cant thank this channel enough. Thanks sir.

Sorry sir but I can't agree with your 'Colour concept'. Because... IF7 is colourless even though its mass and size is maximum. And BrF is Pale Brown Coloured even though the value of 'n' is 1.

Sir can you please provide video lectures on ionic equilibrium especially on buffer solution 😕

[@singhaniaeducation9878]

Sir please chek hybridisation does not takes place in diatomic molecule .it is also mentioned in ncert.dont misguide the students

[@chemistryclassesbyjeet7268]

Clf3, If7, clf3, brf3 reactivitu order

[@sowjanyalucky4815]

Sir in the place of AX we can take any other compounds like IF

[@promemeryt273]

Yes😏

Sir...interhalogen compounds ka upyog bta dijiye plzzzz🙏🙏🙏🙏

[@kehkashakhan2171]

inorganic chemistry concept =mka sir .thank u so much sir

[@humblestudent218]

Sir IF is more polar than ICl or
IBr . So reactivityof IF must be greater .
Then why IF is more thermally stable ?
plse clear my doubt sir ,
humble request
