Chemistry 102: Acid Equilibrium: Lewis Structure

Question

Consider the reaction between HF and SbF₅ to form the strong acid HSbF₆.

 

Use the curved arrow tool on the Lewis structures below to show how electron pairs move, and bonds form and break, in this reaction.

Answer 1

Hello Katelyn!

I am typing out the solution as I am unable to film a video with my iPad.

The arrows determine movement of electrons. The first step would see the curved arrow start at the bond of the H-F molecule going to the fluorine. This produces a hydrogen ion and a fluorine ion. The fluorine ion would then point to the Sb atom as it binds to the central atom. The Sb atom has d orbitals that can hold the extra electrons.

Let me know if you have any further questions, Katelyn!
