Trick for Bond Angle | Developed by IITian | IIT Jee Mains, Advance, NEET, BITSAT & AIIMS

Hello Guys, No need to worry about Bond angle comparison problems, Watch full lecture and be expert in Bond Angle. Let's start:-
Polyatomic molecule has more than one bonds which are formed by overlap of atomic or hybrid
orbitals and due to directional nature of the hybrid or atomic orbitals these bonds make angles between
them. The angles between the lines representing the two bonds are known as bond angles and are
measured by X-ray diffraction and spectroscopic methods. Because of the constant atomic vibrations,
the bond angles thus measured are really average bond angles. The shapes of the molecules are dependent
on the bond angles. The molecule of methane, therefore, is tetrahedral because of the H-C-H bond
angles of 109.5°, the molecule of water is V shaped because of the H-O-H bond angles of 104.5°
and the molecule of NH3 is pyramidal because of H-N-H bond angle of 107°
Bond angles mainly depend on the following three factors:
Hybridization: Bond angle depends on the state of hybridization of the central atom
Hybridization: sp3, Bond angle: 109, Example: CH4
Hybridization: sp2, Bond angle: 120, Example: BCl3
Hybridization: sp, Bond angle: 180, Example: BeCl2
Generally s- character increase in the hybrid bond, the bond angle increases.
Lone pair repulsion: Bond angle is affected by the presence of the lone pair of electrons at the central atom. A lone pair of electrons at the central atom always tries to repel the shared pair (bonded pair) of electrons. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle.
Electronegativity: If the electronegativity of the central atom decreases, bond angle decreases.
One should also keep in mind:-
Triple bonds repel other bonding-electrons more strongly than double bonds.
Double bonds repel other bonding-electrons more strongly than single bonds.
We hope, you will enjoy it.

sir i m from kota...and i can see few important points are missing...Like 1.factors of Central Atom and Terminal Atom factors are applicable only when central atom has atleast one Lone Pair or C.A. forms different types of bond.... Disclaimer:- I have no logic for this point but they are mentioned in the notes provided by Allen Kota

Sir for NO3- bond angle is 120 whereas for NO2 it is 134 but while arranging you gave bond angle of NO3- is greater than bond angle of NO2 . Duration 42:37

[@Anoyartgur]

Yeah bond angle of NO2 is greater than that of NO3-...

[@CRAZYGAMER-sk8xt]

[@Fukira7]

Sir really ,there is lack of teachers like you ,Many teachers which are highly educated don't give proper series of Course on KZbin .They only give one or 2. sir thanks .Really deep knowledge

[@mihirkumarpal2854]

All your videos are effective for clearing concepts and it will be highly beneficial to the medical and eng aspirants. Upload more videos on other chapters.

Sir esme Konsa variation hoga bf3 bcl3 bbr3 bi3 I am not able to understand this as our teacher is saying no variation will occur

[@ManojP847]

BEFORE WATCHING THIS VIDEO THAT I CAN NOT LEARN BOND ANGLE OR HOW TO ARRANGE IT BUT AFTER WATCHING THE QUESTIONS ARE SO EASY FOR ANDI GAIN 100% CONFIDENCE IN BOND ANGLE. THANK YOU SIR VERY MUCH

[@siddhantaroy5432]

Sir NO2 bond angle is 134 degree but NO3 - bond angle is 120 degree. But NO2 has a single electron. So NO2 bond angle should be minimum then no3 -.

[@yashtripathi9]

Plzz arrange them in decreasing order of bond angle or tell which will have highest bond angle....a)Ph3 b) CH4 c) NH3 d) H2O...

[@sahilprasad9185]

Firstly thank you sir. Very nice concept. Sir i want to know that how to calculate elecronegtively for any elements please sir..........

[@ankurkumar-le3hs]

Bond angles of sio4 4-, po4 3-, so4 2-, clo4 - are same. But a/c your rule no 3 bond angle should be in increasing order .

Sir in 40:50 pe, aapne Bond angel to vese hi Bata diya to bond angel ka Inc order a>c>b>d hoga kya is it right sir plz answer I am confused 😕

[@somendratewari6276]

bcz of electronegativity difference Induced negative charge is created as a result lp and induced negative charge repulsive takes place as a result lp move away from central atom as a result lone pair bond pair repulsion decrease hence bond angle increases

[@nilima_jhapate]

Really very helpful 👌

[@saiseema9]

Sir soon you will be one of the famous chemistry teachers in India ☺

[@vatsavmoliya7451]

Sir yeh nai samja ki no2 ka angle no3- se jyda kese even after odd pair repulsion also if repulsion occurs on no2 which is sp2(normal bond angle 120° for sp2) then shouldn't the angle be less than 120°? Plz reply big confusion to me

[@GurmeetSingh-tr3ju]

Same confusion. But sir ne explain krte wakht yeah clear btaya ha ki no3- second place . Phir 134° > 120° toh second place confusion. 😢 help someone

[@mueed181]

Mujhe bhiii

[@anshikajain740]

May be sir ne angle galti se galat likh diya ho... Varna explain karte vakt toh sir ne second position par NO3- and third position par NO2 likha h

[@gopalkrishnaniyogi5941]

No2+,No2,No3-,No2-(from experiment)

[@entertainmentworld5540]

Vo 2 no. Vali structure no2 ki nhi h ...n2o ki h || or us n2o m odd e- or bp repulsion h .. Or no2^- m BP LP repulsion h ||

[@achchenotes6433]

Very very very nice video sir u are really very genius . u are best teacher .

[@harikarthi5139]

sir in your last example of NO2+, NO2 , NO3- , NO2 - , IF WE CONSIDER NO3- , DUE TO RESONANCE ALL BONDS ARE CONGRUENT and its sp2 so bond angle 120 degree, and you explained bond angle in no2 as 134 degree so bond angle order is N02+ > NO2 > NO3- > NO2-, YOU HAVE WRITTEN THE ANGLES CORRECTLY ( 40:56 ) BUT WHILE EXPLAINING YOU UNKNOWINGLY TOLD NO3- IS SECOND POSITION ( 42:48 ) , im just telling this to inform others , thank you sir

[@stritax9478]

43:42 apne kaha second mai NO3-..toh upar NO2 ka NO3- se zyada kyu hai?

[@NurseLifeGlam]

Sir u are best teacher in world ,I have ever seen.....😊😊😊

[@naiyerabbas6481]

sir u are great. Thanks a lot for clearing my doubts and making this comparison look so simple. However I have a doubt in the last question. As u said in the beginning odd electron- bp repulsion is greater than bp-bp repulsion. no2 contains odd electron whereas no3- does not contain any. So as per this concept BA of no2 should be lesser because it has odd electron

[@rajeshjyani1779]

NO2 has larger bond angle than NO3- why?

[@AnkitKumar-go5we]

Sir thank you soo much...your video helps me a lot....!!!

[@aaditysinha8369]

Sir i am from kota allen ;Big variation in B.A from NH3 to PH3 is because of Dragos rule in which no hybridisation take place ! pure P orbita present ! So angle is approx 90

[@dineshjaini3524]

He has considered that

[@g1ntok147]

Pure S orbital actually

[@g1ntok147]

Bond angle 94 deg

[@suryaprasadsarangi1809]

awesome hey are you really a man i think u are beyond that

[@divyanisahu8278]

sir you said that no3 - will be at second posiion ion bond angle in last question but according to the data provided by you no3- is at the third postion

The bond angle of NO2 is 134.3° where as that of NO3- is 120°..how to explain this .....if according to you odd electron-b.p replsn>bp-bp replsn... Sir you got the data correct but explained wrong in the last part of the video

Sir, please upload video on comparison bond length

[@azeemkhan3151]

Sir how will you compare in BF3 BCL3

[@yashtripathi9]

See peripheral atom's EN is inversely proportional to bond angle...so just see EN(F) >EN(CL)..so just judge yourself!!

[@sudakshamalla5810]

This bond angel video very helpful for student especially for me, Thank u so much sir

[@saharshyashasvi9169]

Sir , between H2O and OCl2 , bond angle of ocl2 is more than H2O , but electronegativity of H is less than cl(which obstructs your last point ) . Please explain this
