Question

Can anyone please tell me how to calculate the hybridization?

Answer 1

You can find the hybridization of an atom by finding its steric number: The steric number = the number of atoms bonded to the atom + the number of lone pairs the atom has. If the steric number is 4, the atom is s p 3 hybridized. If the steric number is 3, the atom is s p 2 hybridized

Hybridization is given by the following formula:

H=(1/2)(V+X−C+A)

Where:

• V= number of valence electrons in central atom
• 
  X = number of monovalent atoms around the central atom
• 
  C = positive charge on cation
• A = negative charge on anion

H=4→sp3,
2→sp,
3→sp2
...

e.g.: in NH3, the hybridization of N atom is:

H=(1/2)(5+3−0+0)=4→sp3
