Coordination Compounds

Postby Lusin_Yengibaryan_3B » Thu Nov 26, 2020 1:01 am

What's the difference between an OH2 bond and an H20? Why are bonds written in different atomic order in different parts of a lewis structure and why are the atoms in a molecule sometimes separated in these structures as well? I don't understand how we would determine this and decide where each molecule is bonded and in which atomic order the molecule is written in a specific bond.

I don't think there is a difference between an OH2 bond and an H20. We just write them different in the lewis structure to show that the cation and ions are binding to each other.

Like above, there is no difference in OH2 and H2O. They are just written like that in order to show which atom is actually bonding to the cation. In this case, O (the negatively charged atom) is what's binding to the cation. Therefore, for the purpose of showing which cation and atom are bonding, H2O is sometimes written as OH2

H2O and OH2 is the same compound. In Dr. Lavelle's lecture he wrote them differently as H2O and OH2 in order to should that the lone pairs on the O are the ones that are forming the coordinate covalent bond with the transition metal cation. Usually when atoms are written in different order, they are trying to show what each atom specifically bonds too.

H2O and OH2 is the same compound they are just written in a different order to show that the lone pairs on the O are what is bonding and forming the coordinate covalent bond with the transition metal cation.

Yes, I agree with the other answers given. OH2 and H2O are the same compound, however, it was written as OH2 to show the bonding order.
