Question

The sulfur hexafluoride molecule is nonpolar and contains no lone (unshared) electron pairs on the sulfur atom.Find the bond angles in sulfur hexafluoride molecule:

• A. $120A^{\circ }$
• B. $180A^{\circ }$
• C. $90A^{\circ }$ and $180A^{\circ }$
• D. $90A^{\circ },120A^{\circ }$, and $180A^{\circ }$
• E. $109.5A^{\circ }$

Answer 1

The correct option is C $90A^{\circ }$ and $180A^{\circ }$

The bond angles in sulfur hexafluoride molecule are $90A^{\circ }$ and $180A^{\circ }$. The central S atom in $S{F}_6$ molecule is $s{p}^3{d}^2$ hybridized (due to presence of 6 bond pairs of electrons and 0 lone pairs of electrons) which results in octahedral geometry.
