We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
HgS will precipitate first when tiny amounts of sulfide ion are slowly added to the solution.
<h3>What is Ksp?</h3>
The solubility product constant, Ksp, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution.
If Solubility product is greater than the ionic product then no precipitate will form on adding more solute because unsaturated solution is formed.
If Solubility product is lower than the ionic product then excess solute will precipitate out because of the formation of super saturated solution.
Here, Ksp value of HgS is very low. Hence, HgS will precipitate first when tiny amounts of sulfide ion are slowly added to the solution.

Answer: The correct answer is option B)
in the synthesis of cryolite for aluminum production.
Explanation:
Hydrogen fluoride (HF) is used in synthesis of cryolite for aluminum production.
HF is a gas that dissolves in water to form hydrofluoric acid. However, HF also react with halogenated alkanes like trichloromethane CHCl3 to form organofluorine compounds that serves as precursors in the synthesis of cryolite, an Ore from which aluminum is produced
