VSEPR Trigonal Planar Geometry

BF3 (boron trifluoride) is a molecule representative of trigonal planar geometry & is roughly 300mm (12") along any 2 arms of the molecule when constructed with Unit models.

Compare this to the model from the smaller Orbit Basic VSEPR theory set; the same structure is only 50mm (2") along any 2 arms of the molecule.

-Simon Bott
I recently moved to the UK from the US and needed some classroom-demonstration models. In the US, I had used the horrible polystyrene balls and wooden sticks that were/are so prevalent. They were awkward to use and very fragile. Indeed, after only typically 2-3 uses of a given central atom, at least one "hole" for the sticks had broken. No such issues with the Indigo kit. While it was initially a little tiresome to set up the 5- and 6- coordinate central atoms, they are sturdy and have not (to date) broken. They are easy to transport and visually more appealing than the ones I used previously. While the price might seem a little steep, it is worth it to have a great classroom tool and I recommend them wholeheartedly.

Thanks for the feedback.
