Which substrate below would be the most reactive for an SN1 reaction?

**Question:**

Which substrate below would be the *most* reactive for an S<sub>N</sub>1 reaction?

**Options:**

- **a.** ![option a](https://via.placeholder.com/80)
  
  - Structure: 2-Bromo-2-butene

- **b.** ![option b](https://via.placeholder.com/80)
  
  - Structure: 1-Bromobutane

- **c.** ![option c](https://via.placeholder.com/80)
  
  - Structure: 2-Bromobutane

- **d.** ![option d](https://via.placeholder.com/80)
  
  - Structure: 2-Bromo-2-methylpropane

**Explanation:**

For S<sub>N</sub>1 reactions, the reactivity of a substrate depends largely on the stability of the carbocation formed. Typically, more substituted carbocations are more stable. In this question, you are asked to determine which of the given substrates forms the most stable carbocation, thereby making it the most reactive in an S<sub>N</sub>1 reaction.
