HW Q 4.13

For part a to this question, I thought I3- was supposed to be angular but it says the shape is in fact linear. Can someone explain to me why it is linear. I think the three lone pairs are confusing me. I understand that only atoms are considered when naming VSEPR shapes but lone pairs do alter the shape. Do the three lone pairs cancel out or something?

Yes, the lone pairs do affect the molecular geometry (not the electron geometry). There are specific names for electron geometries with a certain number of lone pairs. Dr. Lavelle has not yet gone through alll of the molecular shapes, but they are in the book at the beginning of the chapter.

Is this helpful in visualizing the molecular geometry?
