10. An amine is typically a poor leaving group. An amine can be converted to a good leaving group when treated with excess methyl iodide. The iodide salt is converted to the hydroxide salt using silver oxide and upon heating an E2 reaction occurs. This synthetic sequence is usually referred to as the Hofmann elimination. The reaction commonly favors the formation of the least substituted alkene. excess CH 31 R-N(CH), 1 Ag,0 - —...

Draw the structure(s) of the major product(s) of the following
reaction after workup to neutralize acid.
You do not have to consider stereochemistry.
Draw one structure per sketcher. Add additional sketchers using
the drop-down menu in the bottom right corner.
Include the counterion when the product is a quaternary
ammonium salt. Draw the counterion in its own sketcher.
Separate multiple products using the + sign from the drop-down
menu.
If no reaction occurs, draw all starting materials.
