Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.This is way beyond what jee would ever ask though but still
This is something similar to the case of CO if you wanna see it like that
Back bonding to the pi star of the N2
Inreases the N-N bond length
But decreases the metal centre and N bond length
That’s how I would do it without much background
There could be some intricacies which I’m not aware of but for the most part… this approach should work
can you explain it by a figure maybe
im not sure how backbonding is happening
aits mein aaya tha karna to chahiye fir
AITS bhi kiska hai 🥀
i have an explanation but usse C aara
galti batado
FIITJEE ka AITS kitna hi relevant hota hai yaar 😭
Batayo chalo
are yar😭
Tumne CO ka diagram dekha hai?
MO?
Vaise hi N2 ka bhi dekha hoga
N2 ka to definitely dekha hoga
N2 jab bond banayega to apna l.p dega, jisse n-n ke lp ki repulsion kam hogi aur bond length decrease hogi
Handwavy
Not very accurate
why so
N2 ka MO Diagram dekho ek baar
Kyunki other factors aa rahe hain
If there is an empty pi star along side
Or titanium ke paas hain lone pairs
Weird
Nahi
Not weird
Okay
hmm isme kya dekha ha ab
Iske baad konsa bhara jayega batayo
Agar bond bana to
Pi Star?
yep
vahi ha agla
To agar titanium isko electrons de
To vo Ti-N bond ka to bonding orbital banega
But
N2 me internally vo Pi Star me jaa raha hai
So technically N2 ka internal bond length badhega
And Ti-N ka 'cause bonding orbital or antibonding dono ban Raha hai with that lone pair usage from N
To unka bond length decrease ho jayega
Got it?
nope
wait
acha titanium ne nitrogen ko elec diye, isliye backbonding
but N pe bhi to elec ha
vo kyu nahi hua
and Ti ne elec diye to bond length increase kese hogaya
Dekho
N ne banaya sigma
Right?
Par vo N or N ka sigma nahi tha na?
Vo to N or Ti ka sigma tha
Ab hua kya
haan sahi baat h
Jo tumhare Ti ke electrons the
Vo backbonding hoke N ke pi star me gaye
Ab N ke pi star me agar electron jayega
To bond length kam hogi
Kiski kam hogi?
N-N ki
pehle to kam kyu hogi
Kyunki unke hi to Pi Star me gaya!
Sorry
Jyada hogi
Ulta bol diya
are sorry yar mai smjh nahi paa raha
2min do
Ruko ek sec
Ye dekh lo
I hope isse aa jaana chahiye
Agar nahi aaya to thande dimag se baad me dekhna
Aa jayega
ACHAAA
are antibonding kehdete mai smjh jata
chalo koina mai smjh gya
.....
Pi star bola to 😭
Chalo koi ni
vo mene dhyan ni diya 😭
Jo bhi ho
Samajh aaya kaafi hai
yep
Same chiz CO me hoti hai
I mean aa hi sakta hai question to
But usually CO ka hi aata hai
koi vo ha isme
kin kin mei aisa hota
Jiske saath bhi laga do
N2 CO anything else
d block me to sabke paas hote hain lone pair
Low lying pi star hona chahiye
Abhi usme mat jaayo
CO
N2
CN
low lying means?
Inka yaad rakho
Low energy
theek ha
oh
Ki vo bond ban paaye
Ki itna ooncha na chala jaaye
mere 2 aur thode conceptual doubt ha chote se idhar hi puchlu?
Ki Ti ke electrons hi nahi reach kar paate
Pooch lo thoda jaldi karna
Apna bhi padhna hai
jo hamara
[Cu(NH3)4]+2 hota ha
usme sp2d and dsp2 dono dekhne ko milti
agar quesn agya konsi leni ha to kya tick maarenge?
Jo NCERT me likha hai dekh lo yaar
Ye hybridisation vaise me bhi galat theory hai to maine kabhi utna dhyaan nahi diya
theek ha
ek last
chalo vo rehn do
vo easy ha khud dekhlunga
Chalo thik hai fir
thanx a lot
