Chemical Sturctures

1. The problem statement, all variables and given/known data

I am attempting to draw 3-ethylbutanoic acid as well I am trying to determine the geometry of (FeCl₄)^- and (Ni(CN)₄)^-2.



Also, can dichlorobisethylenediaminecobalt(III) chloride be expressed as (Coen₂Cl₂)Cl?

2. Relevant equations







3. The attempt at a solution



I think 3-ethylbutanoic acid can look like see attached





Just for clarification a double bond is coming off of the C=O and a single bond off the C-CH₂CH₃



I believe the geometry of (FeCl₄)^- is Tetrahedral and the last one is square planar
