+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.Question 1
Where is back bonding que?
X-y , xeof4 wala question
Is the answer 10?
14
I got 15 lone pairs , but dk how many p pi d pi bonds
15 lp and one pπdπ bond
How come there's only one
Only oxygen bond is p pi di pi
There are vacant d orbitals in xe , and enough lone pairs to give
F second period element h d orbital hota hi nhi
Why not the back bond between f and xe
P toh hai par
F ke pas already sufficient electrons h that is 8
Yeah and xe has vacant d orbitals
So it can share
It wont
This is my understanding of back bonding , lone pairs go from full filled to vacant orbitals
Back bonding to tb krege na jab electron ki kami ho Like in BF3 isme Boron pr e kam hai islie krta h
Ha to kahi bhi back bonding thodi krwa denge
There are certain cases
Boron has vacant p orbital and f has filled p so lone pairs can go forming 3 p pi p pi bonds right ?
yeah
Or only one
P to P bhi kr skta h p to d bhi kr skta h
1 or 3 ?
Boron doesn't have d
General case bol ra hu boron ki baat nhi kr rha hu
pH
If bf3 has 3 p pi p pi bonds why can xeof4 not have 5 p pi d pi bonds
I didn’t get ur point
Here u agreed 3 back bonds in bf3
So how can we calc no of back bonds in xeof4
its not 3 back bond 😭💀
Har F bari bari deta hai
Why u said "yeah" 😭
I thought your 3 means 3rd p orbital
Matlab it keeps on changing but the total number of p pi p pi bonds is 1 only
Woh toh bf3 mein kahin nahi hai
Yup this is correct
Same goes for xeof4?
1 oxygen and 4 f , all 5 can give and keep on changing
Aise toh there can never be more than 1 back bond
but back bonding krege kyu
Think of a reason first
In xeof4 ??
5d orbital is empty , fluorine and oxygen have lone pairs so they will
kya Xe ke pass e ki kami hai?
It is hypervalent dude it has more than 8 e
Back bonding is a special case jo compound show krte hai in raree cases if CA hve deficiency of e
So means zero back bonds in xeof4?
Answer says otherwise
Yeah
Answer says there's 1 back bond
14 h ans?
15 lone pair or ek p pi dp bond dusre comp ka
Yep
So yeah its correct na 15-1 =14
...
I dont think there’s any bb 1 p pi d pi is the double bond
Also back bonding is also a pi bond so shyd aise explain kia ho ans me inhone
If u hve explanation to answer do show it
Nah no explanation
Then yeah there is no bb the one p pi di pi the the double bond between Xe and O
chlo if abhi bhi clear ni hua ill try to answer tomorrow. I gtg to sleep i hve classes in mrng
Can u answer the other one
Super quick
Okk , cya
bhai solved mark kar diya kar xD
@hardcoreisdead
nah i intentionally left it open in hopes of some better opinions on this
