This base-catalyzed isomerization involves the following steps: 1. Deprotonation to form tetrahedral intermediate 1; 2. Collapse of the tetrahedral intermediate and bond cleavage to form enolate ion 2; 3. Proton transfer to form enolate ion 3; 4. Intramolecular aldol reaction to form tetrahedral intermediate 4. Write out the reaction on a separate sheet of paper, and then draw the structure of enolate ion 3.

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
