A disastrous paintball game has left the school a shell of its former self.
Students dart from classroom to classroom in a vision that looks like a scene from an apocalypse

Amidst the ruins of Greendale, one study group must fight...to study another day

 

Mechanism 1

 
 
 
 
DMDO acts on the carbon-carbon double bond of the molecule to create an epoxide. This reaction is done in acetone (57%) and DMDO (41%) over a range of -78 to 23 degrees Celsius. Acetone is formed as a product of the reaction and adds to the solution.
 
 
 
 
 
 

 

Mechanism 2

 
 
 
 
NH4Cl is in solution to act as a mild acid. Protons are constantly being exchanged between the ammonia and chloride ions in a similar manner to a buffer system. The oxygen is then protonated, in the case we've shown, by the HCl.
 
 
 
 
 
 

 

Mechanism 3

 
 
 
 
An azide ion, N3, in solution as NaN3 acts as a nucleophile to attack one side of the epoxide. It seems plausible that tis regiochemistry would be more likely to occur because of the electron-withdrawing group C=O. At this point, the product is acheived, with NH3 and NaCl as by products
