Question

The ground state electronic configuration of S is $3s^{2}3p^{4}$. How does if form the compound $SF_{6}?$

• A. Due to octahedral shape of S atoms
• B. Due to presence of vacant 3d-orbitals which provide 6 unpaired electrons in excited state
• C. Due to $sp^{3}$hybridisation of S atom which provides 6 electrons to 6 F atoms
• D. Due to presence of 3 sigma and 3 pi bonds between S and F

Answer 1

Answer: (B)

Due to presence of vacant 3d-orbitals which provide 6 unpaired electrons in excited state

Answer 2

: S can go into excited state with 6 unpaired electrons due to presence of vacant 3d-orbitals which are overlapped by six F electrons.
