What is the electron geometry of this molecule? alcl3
tetrahedral
triangular planar
bent triangular
pyramidal

The electron geometry of AlCl₃ is triangular planar.

Explanation:

The aluminium atom has 3 electrons in its valence shell. The chlorine atom has 7 electrons in its valence shell. Therefore, each chlorine atom can pair one electron with one electron of the aluminium atom, forming single bonds. The image attached shows how the Cl atoms are arranged around the Al atom.

All the single bonds are in the same plane and the Cl atoms form a triangular shape. This is why the geometry of the AlCl₃ molecule is triangular planar.

Ibelieve its a because an empirical formula usually has a ch in it your options are a or b

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
