7th edition problem 2E.5

Postby Katie Frei 1L » Mon Nov 19, 2018 11:37 pm

For this problem, you have to come up with the shape of a ClO2+ ion. In the solutions manual it says the shape is angular, but that it has an trigonal planar arrangement. Which one of these would be the correct answer/how did the book come up with these answers?

It is a trigonal planar arrangement because there are three regions of electron density, however, it has a bent shape because you only take into account the atoms when naming the shape. I believe the question itself asks for the molecular shape, so bent/angular would be the correct answer. Hope that helps!

The shape of the molecule is angular/bent because one of the regions of electron density around the Cl atom is a lone pair, which is not counted when deciding the name of the shape. However, because there are three regions of electron density around the Cl atom, the electron arrangement is trigonal planar even if the shape is not. Hope that helps!
