Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Draw the expanded structure of Levothyroxine. Illustrate all ways that your molecule could form hydrogen bonds with water. Do this by drawing bent water molecules as necessary and use dashed lines (---) to show H-bonding between water and the appropriate atom in the molecule. Be sure that it is very clear which atoms on each molecule are involved in the hydrogen bonds. Keep in mind that hydrogen bonds from water can only from to the polar parts of your molecule. If your drug molecule is not capable of forming hydrogen bonds with water, fully explain why not.
