**Reaction Mechanism Exercise**

**Copy the figure shown below onto your scratch paper.**

(Box 1) 
\[ \text{C}_x\text{--C}_y + \text{Br} \]

(Box 2) (Empty Box)

(Box 3) (Empty Box)

\[ \xrightarrow{\text{HBr}} \]
\[ \text{C}_x = \text{C}_y \]

**Then, complete the figure on your scratch paper** by drawing out the intermediates and arrow-pushing mechanism in Boxes 1-3 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 \(\text{C}_x, \text{C}_y, \) and bromine atoms in each box, and match the contents of each box to a single phrase (A-H) that best describes the mechanistic step that occurs in each box.**

A. A hydride shift occurs.  
B. A methyl shift occurs.  
C. A nucleophile attacks a tertiary carbocation.  
D. A leaving group leaves.  
E. A nucleophile attacks a secondary carbocation.  
F. Br is protonated, \( \text{C}_y \) is deprotonated, and a pi bond forms.  
G. A carbocation attacks the Br.  
H. Br is protonated, \( \text{C}_x \) is deprotonated, and a pi bond forms.

**\(\text{C}_x \text{ formal charge (+,-,0)}\) \(\text{C}_y \text{ formal charge (+,-,0)}\) \(\text{Br formal charge (+,-,0)}\) Phrase (A-H)**
