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:**
Which one of the following are different from the others?
**Structures:**
1. CH₃CH₂ (attached to a carbon with) H and Br in wedged and dashed bonds, respectively, and another CH₃.
2. Br (attached to a carbon with) H in wedged, CH₂CH₃ in dashed, and CH₃.
3. CH₂CH₃ (attached to a carbon with) H in dashed, Br in wedged, and another CH₃.
4. Br (attached to a carbon with) CH₃, H in dashed, and CH₂CH₃ in wedged.
**Options:**
- ○ 1
- ○ 2
- ○ 3
- ○ 4
**Explanation:**
This is a stereochemistry question focusing on the arrangement of atoms in 3D space, using wedge-and-dash notation to indicate different spatial orientations. The aim is to determine which structure is different, suggesting an enantiomer or a structural isomer among the given options.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbba9f6c6-d2a1-4bca-bdf9-0111cddb17f4%2F071f5796-7e4c-4920-8ca2-b3f998444f71%2Fvnpaa07_processed.jpeg&w=3840&q=75)
