AI Thread Summary
H2O and OH2 are often used interchangeably when referring to water as a ligand in complex entities, as both denote the same molecular structure. The distinction primarily lies in emphasizing the oxygen atom as the donor in coordination chemistry. While some texts may prefer one notation over the other, the chemical behavior remains consistent. The choice of notation does not affect the ligand's function in complex formation. Understanding this nuance helps clarify the role of water in coordination compounds.

How are H20 and OH2 different?
 
I don't think they are different but my chemistry textbook uses OH2 in some complex entities. So I wanted to know if it was so because oxygen is the donor atom in the ligand.
But if it is so then why use H2O, when denoting water as a ligand in some cases?

There is no reason except to emphasize that the bonding occurs through the oxygen.
 
Thanks a lot for clearing my doubt.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
