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 15 of 48**
**Identify the circled functional group.**
[Image: Structural diagram of a chemical compound, featuring an -OH group circled with a dashed line on the right side.]
**Options:**
A) Ether
B) Alcohol
C) Amine
D) Alkyne
E) Alkene
**Explanation of Diagrams and Graphs:**
The diagram presented is a structural representation of an organic molecule. The specific part of the molecule enclosed in a dashed circle contains the functional group -OH, which is called a hydroxyl group.
---
**Answer:**
The correct answer is **B) Alcohol**.
The circled functional group is an alcohol, characterized by the presence of a hydroxyl group (-OH) attached to a carbon atom. This group makes the compound an alcohol, differentiating it from ethers, amines, alkynes, and alkenes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff1fc3c1b-8869-498d-b8c7-2c621535c5fb%2F31894ccf-95aa-4404-8c91-5be6691bd75d%2Fjeqsr3s_processed.jpeg&w=3840&q=75)
