Of the following molecules which are completely planar (all of the atoms in the molecule are located in the same plane, all the time)?Explanation / Answer
6)
oxidation state of Cl is -1 and there are 2 Cl
oxidation state of H2O is 0
To balance charge, oxidation state of Cu is +2
Answer: b
7)
en is bidentate ligand
So, 2 en means there are cordination number of 4
charge of Cl is -1 and there are 3 Cl atoms
en is neutral
To balance charge, oxidation state of Fe is +3
Answer: f
