Add lone pairs to these lewis structures of interhalogen compounds brf3 brf5

Explanation:

1.Halogen elements have different electro-negativity.  

“The binary compounds formed by halogens amongst themselves are known as  Inter-halogen compounds”.  

2.The inter-halogen compounds may be regarded as the halide of the more

electronegative halogen.  

Thus, since the electro positive character of halogens is

in the order F < Cl < Br < I

3. Since F has the least electropositive character, amongst inter-halogen compounds

4. Inter-halogens can be grouped into four categories: AB, AB3, AB5, and AB7. Here

A halogen atom is more electropositive and larger in size than B halogen atom.

5. The oxidation state of atom A in AB, AB3, AB5, and AB7 molecules is equal to

+1, +3, +5 and +7 respectively.

6 .As the ratio between the radii of A and B atoms increases, the number of halogen

atoms per molecule increases.
