Question

Can anyone tell me how do I find the%ionic character to find the covalent character

Answer 1

We can calculate the ionic character of any molecule if we know the electronegativity values of both the atoms which are sharing an electron cloud (sharing an electron cloud = forming a covalent bond) by using the following formula :

If two atoms A and B are forming a covalent bond , A-B, then

Percentage of ionic character

= [16 |(Ea - Eb)|+ 3.5 |(Ea - Eb)|^2 ]

Where Ea = Electronegativity of atom A

Eb = Electronegativity of atom B

| (Ea - Eb) | = The subtraction will give a positive value always since modulus (|| = modulus) sign is used !
