### Reaction Scheme Overview

This image outlines several organic reaction schemes involving alcohols and their transformations using different reagents and conditions. Each reaction is associated with a figure placeholder that might indicate the product or related data.

#### Reaction 1

- **Starting Material**: A tertiary alcohol with a neopentyl structure.
- **Reagents**:
  1. Sodium hydride (NaH)
  2. Methyl iodide (CH₃I)
- **Product**: The structure is not shown (indicated by a shaded box). This reaction sequence typically involves the conversion of alcohols to ethers, possibly forming a methyl ether.

#### Reaction 2

- **Starting Material**: A brominated cyclopentanol derivative.
- **Reagent**: Potassium hydroxide (KOH) in ethanol.
- **Product**: The structure is not shown (indicated by a shaded box). This setup suggests an elimination reaction to form an alkene.

#### Reaction 3

- **Starting Materials**:
  - Phenethyl alcohol
  - Ethanol
- **Reagent and Condition**: Concentrated sulfuric acid (H₂SO₄), heat.
- **Product**: The structure is not shown (indicated by a shaded box). Catalytic acid and heat often suggest etherification or dehydration reactions.

#### Reaction 4

- **Starting Material**: A benzyl alcohol derivative with two hydroxyl groups.
- **Reagent and Condition**: Concentrated sulfuric acid (H₂SO₄), heat.
- **Product**: The structure is not shown (indicated by a shaded box). This condition may result in dehydration to form an alkene or further condensation reactions.

These reaction schemes provide insight into common transformations in organic chemistry, highlighting the roles of reagents like NaH, CH₃I, KOH, and H₂SO₄ in facilitating various types of reactions such as etherification, elimination, and dehydration.
