![2. Number all atoms (except Hs), add lone pairs, add formal charges, and give the mechanism arrows for the reaction below:
\[ \text{Br} \, - \, \equiv \quad + \quad \odot \, / \, \backslash \quad \rightarrow \quad \equiv \quad + \quad \text{HO} \, - \, / \, \backslash \quad + \quad \text{Br} \]
### Explanation of the Reaction Diagram:
- The diagram shows a reaction involving a molecule with a bromo-alkyne and a cyclic ether.
- The product formation is illustrated with an alkyne, an alcohol, and a bromide ion.
- The arrow indicates the direction of the reaction from reactants to products.
### Steps for Completing the Task:
1. **Numbering Atoms:** Ensure that all carbon atoms and other relevant atoms in the structures are numbered consistently (excluding hydrogens).
2. **Adding Lone Pairs:** Identify and clearly illustrate the lone pairs on atoms, especially on oxygen and bromine.
3. **Identifying Formal Charges:** Calculate and indicate formal charges on relevant atoms in both reactants and products.
4. **Mechanism Arrows:** Add arrows to show the flow of electrons in the reaction mechanism, generally from electron-rich to electron-deficient areas.
