### Identifying Reaction Mechanisms

In this exercise, students are asked to identify several organic reaction mechanisms as SN1, SN2, E1, or E2. Each problem includes a reactant structure, reaction conditions, and space to identify the mechanism type. 

---

- **Reactant:** A cyclic alkyl iodide
- **Reagents:** CH₃OK / CH₃OH
- **Mechanism Type:** [Space provided for answer]

---

#### Reaction 2
- **Reactant:** Chlorocyclopentane
- **Reagents:** CH₃OH / KOH
- **Mechanism Type:** [Space provided for answer]

---

#### Reaction 3
- **Reactant:** Bromocyclohexene
- **Reagent:** H₂O
- **Mechanism Type:** [Space provided for answer]

---

#### Reaction 4
- **Reactant:** 2-Chloro-2-methylbutane
- **Reagents:** (CH₃)₃COK / (CH₃)₃COH
- **Mechanism Type:** [Space provided for answer]

---

#### Reaction 5
- **Reactant:** 3-buten-1-ol
- **Reagent:** H₂SO₄, Δ (heat)
- **Mechanism Type:** [Space provided for answer]

### Explanation

- **SN1 Reaction:** Involves a two-step substitution mechanism where the leaving group departs before the nucleophile attacks, typically involving tertiary carbons.
- **SN2 Reaction:** Involves a one-step substitution mechanism with direct displacement of the leaving group by the nucleophile, usually involving primary carbons.
- **E1 Reaction:** A two-step elimination mechanism forming alkenes, generally observed with weak bases and tertiary carbons.
- **E2 Reaction:** A one-step elimination mechanism typically using strong bases, leading to the formation of alkenes.

Students should analyze each reaction's structural elements and reagent conditions to correctly identify the mechanism types.
