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.

**Image Transcription:**
**Instruction:**
Draw the curved arrow notation and predict the products when one equivalent of methoxide in DMSO at room temperature is added to 5-bromo-1-iodopentane.
**Part 1:**
- **Reaction Scheme:**
- A diagram depicts the structural formula of 5-bromo-1-iodopentane.
- The reaction is shown in the presence of methoxide ions (CH3O-) in DMSO solvent.
- Curved arrows are to be drawn to indicate the flow of electrons during the reaction.
**Instructions on Diagram:**
- **Draw the curved arrow notation.**
**Attached Tools:**
- Chemical editing tools for drawing structures and arrows.
**Part 2:**
- **Question:**
Select the major byproduct.
- **Choices:**
- A. I⁻
- B. HI
- C. CH₃OH
- D. Br⁻
- E. HBr

**Graph/Diagram Explanation:**
The diagram represents a typical nucleophilic substitution reaction (S_N2 reaction) where the methoxide ion acts as a nucleophile attacking the electrophilic carbon atom bonded to the iodine atom in 5-bromo-1-iodopentane. The curved arrow notation should depict the methoxide ion's electron pair attacking the carbon and the simultaneous departure of the iodide leaving group. The products are expected to be 5-methoxypentane and iodide ion (I⁻) as the likely major byproduct.
**Note:**
Students are encouraged to use the provided tools to practice drawing the mechanism and to critically think about the reaction process and products. Understanding the electron flow helps in mastering organic reaction mechanisms.
Always refer to a periodic table or use available hints if needed.
