Explanation:
Electron pairs about the central element in simple binary compounds can be determined as follows:
Total e⁻ pairs = Bonded e⁻ pairs + Non-bonded e⁻ pairs
Example:
Given XeF₄ determine the total e⁻ pairs about the central element Xe.
Bonded e⁻ pairs = #substrates bonded to central element
= 4 Fluoride atoms
=> 4 Bonded e⁻ pairs
Non-bonded e⁻ pairs = [Valence# - Substrate#] / 2
Valence# = Xe + 4F = 1(8) + 4(7) = 36 valence e⁻s
Substrate# = 4F = 4(8) = 32 bonded e⁻s (about central element)
Non-bonded e⁻ pairs = V# - S# / 2 = 36 - 32 / 2 = 4/2 = 2 non-bonded pr.
Total e⁻ prs around central element = Bonded Pr e⁻ + Non-bonded e⁻
= 4 + 2 = 6 e⁻ pairs
This implies a Trigonal Bipyramidal parent geometry with a Square Planer molecular geometry.
