Question
Copy the figure shown below onto your scratch paper:
Box Na SCHa
Box 2
Na
SCHa
Then, complete the figure on your scratch paper by drawing out the intermediates and arrow pushing mechanism in Boxes 1-2 that explain the formation of the final products shown. You should start your arrow pushing in Box 1 and you will use all boxes.
Now, report the formal charges (+, 0, -) that appear on the sulfur, bromine, and alpha carbon atoms in each box, and match the contents of each box to a single phrase (A-G) that best describes the mechanistic step that occurs in each box.
A. A nucleophile attacks tertiary carbocation.
B. A nucleophile attacks secondary carbocation.
C. A nucleophile attacks and leaving group leaves.
D. Br is protonated and S is deprotonated.
E. A leaving group leaves.
F. S is protonated and Br is deprotonated.
