How to find Bond Order ? | Trick 😮‍💨

What is Bond Order?
Bond order shows the bond(number of chemicals) that are present between pair of atoms.

FORMULA :-
1/2 [Nb - Na]
Na = number of antibonding electrons
Nb = number of bonding electrons

How to find bond order?

Follow these simple steps to get the bond order of any of the elements:-


Step1
First, you have to find the no. of electrons in a given compound or molecule. For example:-
The question is to find the bond order of N2
Then no. of electrons in this molecule is 7+7 = 14
Similarly, for CN- compound, it will be 6+7+1 = 14; for F2 it will be 9+9= 18.


Step2
After adding no. of electron, you will get numbers   like 10,11,12,13,14,15,16....etc.
📝Now, remember this table-
No. of electrons    Bond Order
10              -            1
11              -            1.5
12             -             2
13             -            2.5
14             -             3
15             -            2.5
16             -             2
17             -             1.5
18             -              1
It shows that if you get no. of electrons as 14 then bond order will be 3, Similarly for 13 bond order will be 2.5
It means you have to subtract 0.5 in going up and down by 14 electrons for one step.

Hurrah !! You get the answer

* Important terms related to Mirrors *

1. Pole: The centre point of the mirror through which the principal axis passes through the mirror is called the pole.

2. Principal axis: The straight line that will pass through the pole and the centre of curvature is called the principal axis.

3. Centre of curvature: The centre of the sphere of which the mirror or lens is a part is called the centre of curvature.

4. Radius of curvature: The radius of the sphere of which the mirror or the lens is a part is called the radius of curvature.

5. Focal point or focus: It is a point at which all the rays meet and we get a sharp image.

6. Focal length: The distance from the pole to the focal point is called the focal length.
