Do you know magic tricks to find hybridization

Magic tricks to find Hybridization

Understand the following formula (X)

X= (number of valence electron on central atom+ negative charge -positive    charge +no of monovalent atom)

Note:

The  number of  monovalent atom mean, having one valency belong to group 1 and 17 ( H, F, Cl, Br)+and–sign on ion will not be counted but values of charge will counted, Such as  in CO₃^2- , we will consider value 2 but sign( –) will not be counted. Different X values with different hybridization are shown below (table 1)

 Table.1 Different X values with different hybridization

Example:

 1.  NH₃  

X= ½ (5+ 0 – 0 + 3) =  4        Sp³   

2.    CO₃^2-

X=     ½ (4+ 2– 0 + 0) =  3     Sp² 

3.  NH₄¹⁺ 

X= ½ (5+ 0– 1 + 4) =  4         Sp³

 4.    XeO₂F₂         

X= ½ (8+ 0– 0 + 2) =  5       Sp³d

Note:

This works in at least  98% of the cases you will see in  inorganic and Organic simple molecule
