Options
- A. A
- B. B
- C. C
- D. D
Answer
A. A
Step-by-step solution
The central atom in XeO_6^ 4- is Xenon (Xe). The number of valence electrons in Xe is 8. Let the oxidation state of Xe in XeO_6^ 4- be x. x + 6(-2) = -4 x = +8 Since the oxidation state of Xe is +8, all 8 of its valence electrons are involved in bonding with the 6 oxygen atoms. There are no non-bonding electrons left on the central atom. Number of lone pairs on Xe = 0 Xe forms 6 bonds with the 6 oxygen atoms (and 2 bonds to satisfy its +8 oxidation state and minimize formal charge). Number of bond-pairs = 6 Total number of bond-pairs and lone pairs around the central atom = 6 + 0 = 6. Answer: 6
