Diol

In chemistry there are so many chemical compounds that have a hydroxyl group but a chemical compound having two hydroxyl groups (-OH) is termed as a diol. It also implies the presence of two alcohols whereas polyols contain two or more than two hydroxyl groups (-OH). Glycol or 1,2-diol is an aliphatic diol that has two alcohol groups on adjacent carbon atoms. In industries, the most commonly used diol is ethylene glycol.

4b）Give the mechanisms for the following:

### Ether Cleavage Reaction with Hydrobromic Acid

#### Reaction Description

This image illustrates the cleavage of diethyl ether using hydrobromic acid (HBr). The chemical equation is as follows:

\[ \text{(C}_2\text{H}_5\text{)}_2\text{O (Diethyl Ether)} + 2 \text{HBr} \rightarrow 2 \text{C}_2\text{H}_5\text{Br (Ethyl Bromide)} + \text{H}_2\text{O} \]

#### Mechanism

1. **Protonation of Ether**: The ether oxygen is protonated by HBr, making the ether more susceptible to nucleophilic attack.

2. **Nucleophilic Attack**: The bromide ion (\( \text{Br}^- \)) attacks the protonated ether, leading to the displacement of an alcohol and formation of ethyl bromide.

3. **Formation of Products**: The reaction produces ethyl bromide (\( \text{C}_2\text{H}_5\text{Br} \)) and water (\(\text{H}_2\text{O}\)).

#### Diagram Explanation

- **Left Side**: The reaction begins with diethyl ether, represented by two ethyl groups attached to an oxygen atom.

- **Middle Arrow**: The arrow indicates the progression of the chemical reaction when two equivalents of hydrobromic acid (HBr) is added.

- **Right Side**: The products are ethyl bromide and water. Ethyl bromide features an ethyl group bonded to a bromine atom, and water is represented by its molecular formula \(\text{H}_2\text{O}\).

This reaction is a classic example of acidic cleavage of ethers using strong acids like hydrobromic acid, where the ether bond is broken to form alkyl halides and water.
