**Which of these would be the best electrophile for an S<sub>N</sub>1 reaction?**

A) CH<sub>3</sub>Br
B) (CH<sub>3</sub>)<sub>3</sub>CBr
C) (CH<sub>3</sub>)<sub>3</sub>CO<sup>−</sup>
D) CH<sub>3</sub>O<sup>−</sup>

*Explanation:*
In an S<sub>N</sub>1 reaction, the best electrophile is one that can form a stable carbocation. Typically, tertiary carbocations are more stable than secondary or primary ones due to hyperconjugation and inductive effects.

- **Option A (CH<sub>3</sub>Br)**: Methyl bromide forms an unstable methyl cation.
- **Option B ((CH<sub>3</sub>)<sub>3</sub>CBr)**: Tertiary butyl bromide forms a stable tertiary carbocation.
- **Option C ((CH<sub>3</sub>)<sub>3</sub>CO<sup>−</sup>)**: Presents as a negative ion, not suitable as an electrophile.
- **Option D (CH<sub>3</sub>O<sup>−</sup>)**: Also a negative ion, unsuitable as an electrophile.

Thus, the best choice for an S<sub>N</sub>1 reaction is **Option B** - (CH<sub>3</sub>)<sub>3</sub>CBr.
