Reactions of Ethers
Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.
Epoxides
Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.
Williamson Ether Synthesis
An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.
Question
Transcribed Image Text:### Chemical Reaction Mechanism
**Reaction Description:**
Using curved-arrow notation, draw out the mechanism for the following reaction. Be sure to include stereochemistry and show all intermediates as well as the final product and include all lone pair electrons.
**Reaction:**
**Reactants:**
- There is an organic molecule with a double bond between two of its carbon atoms.
**Reagents:**
- \( \text{Br}_2, \text{H}_2\text{O} \)
**Products:**
- The product shown on the right has the bromine (Br) and hydroxyl (OH) groups attached to the carbon atoms that were originally double-bonded in the reactant.
**Graphical Representation:**
1. **Reactant:**
- A structure depicting an organic molecule (likely an alkene) with a double bond between two carbon atoms.
- The double bond is represented by two parallel lines between the carbon atoms.
2. **Arrow Indicating Reaction:**
- An arrow points from the reactant to the product, symbolizing the transformation.
3. **Product:**
- In the product structure, the addition of bromine (Br) and hydroxyl (OH) groups can be observed on the two carbons that were originally connected by a double bond.
- The bromine atom is bonded to one of the carbon atoms.
- The hydroxyl group (OH) is bonded to the adjacent carbon atom.
**Explanation of the Mechanism:**
- A detailed description of the addition reaction mechanism should be provided, including the stereochemistry.
- This typically involves illustrating the intermediate steps where the double bond reacts with Br2, followed by the addition of water (H2O) leading to the formation of the bromohydrin product.
**Steps:**
1. **Formation of Bromonium Ion:**
- The double bond reacts with Br2 to form a bromonium ion intermediate.
- Show the curved-arrow notation indicating the movement of electrons from the double bond to one of the Br atoms, and from Br-Br bond to the lone pair on the other Br atom.
2. **Nucleophilic Attack by Water:**
- The water molecule attacks the more substituted carbon of the bromonium ion, opening the three-membered ring.
- Illustrate this step with appropriate curved arrows.
3. **Formation of the Bromohydrin:**
- Deprotonation of
