Mam nowonly i have seen your video i have doubt bond order of CN+ is 3 but; Electrons of C is 6 and N is 7 so total 13 and for CN+ have to subtract 1 element so it will be 12 then bond order will be 2 🤔🤔pls reply mam
Dear student the bond order of CN+ is 2 with :C=N: + structure. Total electrons 6+7-1=12 And its CN- whose bond order is 3 Total electrons=6+7+1=14 with structure - :C triple bonded with N: the negative charge is on Carbon. check CN+ and CN- structures on internet. Hope this helps thank you.🙂💕
your most welcome practice this trick vigorously as definately two questions are going to come from bond order, paramagnetism, diamagnetism, hybridisation sp sp2 sp3 etc.😊🙏 Thank you for liking the trick.🤗
O3 has two resonating structures and if we consider any one side of the two structures and count the number of bonds then it is 1+2=3 bonds on one side so bond order is 3/2 = 1.5 so bond order of O3 is 1.5
see the below comments i have mentioned the method there for electrons greater than 18. Otherwise in short u have to draw structure of that molecule/compound/species and then find out with a special method of counting bonds considering any one side and divide that number by the number of resonance structures of that species.
First of all bond order requires at least 2 atoms to make a bond then only we can find the bond order.A single atom does not make any bond it needs a partner to make a bond like O2 have two oxygen atoms which makes a bond.
Paramagnetic if species contains odd No. of electrons or exceptions 10/16/32 No. of electrons eg- NO 7+8=15 electrons which is an odd No. hence paramagnetic. eg-B2 5+5=10 electrons O2 8+8=16 electrons these are exceptions. Diamagnetic if species contains even No. of electrons . eg-N2 7+7=14 electrons which is an even No. so its diamagnetic. Odd No. 1,3,5,7,9,11,13,15,17,19,21... even No. which comes in table of 2 2,4,6,8,10,12,14,16,18,20...
Ok sure 😊👍 If you learn the concept of bond order then bond angle and bond length are also interlinked. So it will be easier for you.☺👍 Stay connected videos very soon🤗
The bond order for C2 2- is 6 electrons for one carbon and 6 electrons for another carbon plus two electrons which it gains 6+6+2=14 electrons Bond order is 3
see the pinned comment of Mark Thompson and my reply in that i have mentioned bond orders of less than 10 electron species. And for more than 18 electrons you have to draw all the resonance structures of the molecule and take only one side and count all the bond no. of that side in different resonance structures divide that number by the total no. of resonance structures. you will get the Bond Order. For example CO3^2- have 4 bonds on the same side in different structures and have 3 resonance structures. So 4/3 = 1.33 is the bond order.
On left hand side I have written No. of electrons from 10 to 18 And on right hand side I have written Bond Order. All those numbers are based on formula and findings using different elements and electron species.
For ions you need to count them as if charge is + then that species loses an electron then -1 electron from total no. of electrons if -ve then that species gain an electron then add up an electron . For eg CN- Total no. of electrons 6+7+1=14 means bond order is 3 eg O2 2- Total no. of electrons 8+8+2=18 bond order is 1 eg O2+ Total no. of electrons 8+8-1=15 bond order is 2.5
No there is no similar trend but we can say for smaller than 18 electrons we have some fixed values like 0,0.5,1 but for electrons greater than 18 we have different values
🎀For CO2 Total No. Of electrons are 6+2×8=22 Which is greater than 18 electrons . So we use another trick to find its bond order that is 🖍Draw the structure of CO2 means join two bonds between carbon and oxygen on both the sides to satisfy the valency of carbon that is four bonds attached to it. 🔎Now choose either one side left or right and count the No. of bonds between carbon - oxygen . 🖋We have 2 bonds so the BOND ORDER of CO2 is 2
Thank you for connecting to shivani exam solutions.😊👍 The Bond Order for O2- is 1.5 because Oxygen + oxygen + 1 electron(as it have negative charge means gain one electron) = 8+8+1=17 electrons. And bond order for 17 electrons is 1.5 If you have any question then please ask ,Thank you👍
here 20 means those species which contains 20 electrons and more than that. For example CO2 (carbon dioxide) which contains 22 electrons (6+8+8) and its bond order is 2 by drawing its structure O=C=O
The Bond order of He2-1 is 0.5 Because for He (Helium)the atomic No.=2 Here we have 2 He so 2+2=4 electrons Also there is a negative charge means gain of an electron. So in totality there are 5 electrons and for 5 electrons ,the Bond order is 0.5. I have an awesome trick to find the bond order of all the electron numbers starting from 1 to so on.I will make a video for that very soon. thank you😊👍
Yes the bond order of He2 is 0. But in the above comment to mark Thompson I have mentioned the bond order of He2-1 (Helium 2 having one negative charge) means five electrons means bond order is 0.5. Thank you for connecting to Shivani Exam Solutions😊👍
Thank you for connecting to "Shivani Exam Solutions".😊👍 The bond order of Cl2 can be find simply by drawing its structure. Like Cl-Cl Here Cl is bonded by a single bond so its bond order is one. Chlorine atomic no. is 17 so electronic configuration is 2,8,7 Means 7 electrons in the outermost shell so it needs only one electron to complete its octet. So it makes only one bond with another chlorine atom and both get stable. So bond order of Cl2 = 1
Thank you 😊👍 for comment and connecting with" shivani exam solutions". The bond order of CN is 2.5 as electrons sum is 6 + 7=13 and that of CN- is 3 as electrons sum is 6+7+1=14. Hope this will help you. Ask if you have any other questions or doubt. I will try to solve it. Thank you👍

Bond order ke liye class11 chapter4 chemical bonding and molecular structure me dekho usme bond order ka topic hai. waha se samajho aur nhi samajh ata h to comment kr k puchna
For more than 20 electrons species there are different methods. The 2 most used methods are-- (1) use this formula Bond order= valency of attached element + charge on attached element Divided by total no. Of attached element For example--- ClO4 - Here attached element is oxygen(O) And central element is chlorine(Cl) B.O.= valency of oxygen + charge on oxygen Divided by total no. Of oxygen atoms B.O.= 2 + (-1)/4 = 8-1/4 =7/4 B.O.=1.75 (2) in this method draw the resonating structures of the compound Then take any one side in consideration and count the no.of bonds on that side. And then count The no. Of total resonating structures Now use this formula B.O.= No. Of Bonds/ No. Of resonating structures For Example CO3 2- B.O.= 4/3 = 1.33 If have any doubt then please ask us. Thank you for connecting to Shivani Exam Solutions. 😊👍
No sakshi soni Cl2- is 7+7+1=15 so bond order is 2.5 in that way. As -ve sign means gain of electron so you have to add up that electron. Hope you have understood 🤗 Thanks

O2 8+8=16 electrons these are exceptions.
Diamagnetic if species contains even No. of electrons .
eg-N2 7+7=14 electrons which is an even No. so its diamagnetic.
Odd No. 1,3,5,7,9,11,13,15,17,19,21...

What to do for those having sum greater than 18
refer to the comments below i have mentioned there
Can we say that bond order have same trend for sum of electron smaller than 10 or greater than 18....
No there is no similar trend but we can say for smaller than 18 electrons we have some fixed values like 0,0.5,1
but for electrons greater than 18 we have different values
Then bond order for CO2 is?
🎀For CO2
Total No. Of electrons are 6+2×8=22
Which is greater than 18 electrons .
So we use another trick to find its bond order that is
🖍Draw the structure of CO2 means join two bonds between carbon and oxygen on both the sides to satisfy the valency of carbon that is four bonds attached to it.
🔎Now choose either one side left or right and count the No. of bonds between carbon - oxygen .
🖋We have 2 bonds so the BOND ORDER of CO2 is

Ho to find when it is more than 20
Oooo Bhai 20 ke upar bond kisi ka nhi hota
here 20 means those species which contains 20 electrons and more than that. For example CO2 (carbon dioxide) which contains 22 electrons (6+8+8) and its bond order is 2 by drawing its structure
O=C=O
whats is the BO of He2 -1
The Bond order of He2-1 is 0.5
Because for He (Helium)the atomic No.=2
Here we have 2 He so 2+2=4 electrons
Also there is a negative charge means gain of an electron.
So in totality there are 5 electrons and for 5 electrons ,the Bond order is 0.5.
I have an awesome trick to find the bond order of all the electron numbers starting from 1 to so on.I will make a video for that very soon. thank you😊👍

Can u tell me CN can be isolated instead of CN-
If you isolate CN then obviously it will contain some charge.

Phle confuse hoo gy thhee hum
For more than 20 how to find out
For more than 20 electrons species there are different methods.
The 2 most used methods are--
(1) use this formula
Bond order= valency of attached element + charge on attached element
Divided by total no. Of attached element
For example---
ClO4 -
Here attached element is oxygen(O)
And central element is chlorine(Cl)
B.O.= valency of oxygen + charge on oxygen
Divided by total no. Of oxygen atoms
B.O.= 2 + (-1)/4
= 8-1/4
=7/4
B.O.=1.75
(2) in this method draw the resonating structures
of the compound
Then take any one side in consideration and count the no.of bonds on that side.
And then count The no. Of total resonating structures
Now use this formula
B.O.= No. Of Bonds/ No. Of resonating structures
For Example
CO3 2-
B.O.= 4/3
= 1.33
If have any doubt then please ask us.
