This seems kind of dumb, but can someone explain what the angular shape is? I see it in the book but it isn't very well explained and I don't remember Lavelle going over it in lecture. An example is #5

An angular molecular shape is the same thing as bent. There are two types of shapes that can be called "bent" or "angular". The first is a molecule with the central atom having three areas of electron density, with two atoms and one lone pair. The other type of bent/angular shape is a molecule with four areas of electron density, two atoms and two lone pairs. Both these structures causes a "bent" shape, the same thing as angular. A common example of a bent or angular shape is water, H2O. ;)
