**Analyzing Two S<sub>N</sub>2 Reactions**

The table below provides a detailed analysis of two S<sub>N</sub>2 reactions through a series of questions. Each question corresponds to specific concepts in organic chemistry, focusing on nucleophile behavior, Lewis structures, resonance structures, and reaction mechanisms.

| Rxn →                            | NaNCS          | H<sub>3</sub>C          |         I →        | H<sub>3</sub>C         | SCN +        | ⦵                              | NaNCO         | H<sub>3</sub>C          | I →         | H<sub>3</sub>C         | NCO +        | ⦵                             |

| **Draw a Lewis structure for the nucleophile used in this rxn which takes into account the spectator ion.** | | | | | | | | | | | |
| **Draw a resonance structure that shows an additional site of nucleophilicity in the nucleophile.** | | | | | | | | | | | |
| **Draw an S<sub>N</sub>2 mechanism for the given rxn.** | | | | | | | | | | | |
| **Why did the nucleophile attack from the site it did?** | | | | | | | | | | | |
| **Which rxn do you think is faster/slower than the other?** | | | | | | | | | | | |
| **Why do you think each rxn is faster/slower than the other?** | | | | | | | | | | | |

**Description of Reactions:**
- **Reactants and Products:**
  - The first reaction involves NaNCS with CH<sub>3</sub>I, resulting in CH<sub>3</sub>SCN and a by-product.
  - The second reaction involves NaNCO with CH<sub>3</sub>I, resulting in CH<sub>3</sub>NCO and a by-product.
