Trigonal planar vs Bent

Postby FizaBaloch1J » Sun Jun 10, 2018 12:05 pm

For Hw question 4.5 when drawing the lewis structure for ClO2+ the answer says the arrangement is trigonal planar, but I thought it would be bent because their are 3 "things" connected to the central atom of Cl, one being a lone pair and 2 bonds. So I am confused to how the solution says its trigonal planar.

The shape for ClO2+ lewis structure is bent considering the placement of the atoms around the central atom. Since, there are unbonded electrons attached to one side of the atom, this creates a trigonal planar arrangement. In this case shape and arrangement are different and both are provided as an answer, but the shape of ClO2+ is bent. Really hope this helps!
