Re: What is the shape of [Fe(dien)2]^2+

Dien is a tridentate because because it has 3 atoms capable of binding to the central atom. If you look at the full chemical formula, it is NH2CH2CH2NHCH2CH2NH2 (look at page 101 of the course reader for a cleaner representation) There are 3 nitrogen atoms, and they are the only ones capable of bind...

Idean showed another way during his midterm review that really helped me. Think of each region of electron density as a way of counting the hybridization The first region of electron density is s The second region of electron adds another letter, so sp The third region of electron density adds anoth...

So a Bronsted acid is a supplier of a type of Lewis acid, a proton. The start of Chapter 11.2 goes into detail if you want...
