Cis- versus Trans-

Postby Kathleen Nguyen 3G » Sat Nov 12, 2016 9:37 pm

I know that these prefixes have some relevance in the biological significance of coordination compounds, but why? Why is it crucial that two of the same element/atom are side by side versus opposite in a molecule?

I believe that the difference between whether or not the molecule or element is side by side or opposite each other is how they enable bonding between other molecules. The different positions would allow the molecule to bind to, say proteins, differently if they are orientated differently, and their general reactivity with other molecules/elements would determine their biological significance. Please correct me if I am wrong.

You're totally correct but just to add to that, if the compound is cis- then the same elements on the same side can bind in two places to the Lewis Acid versus only one being able to form a coordinate covalent bound if the molecule was trans-.
