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.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
