HS. H3C Question 16 of 48 The structure of penicillamine is shown below. Which of the following functional groups is indicated by the box? A) alcohol CH3 B) ketone HU P1C NH₂ OH aldehyde D) carboxylic acid
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 16 of 48**
The structure of penicillamine is shown below. Which of the following functional groups is indicated by the box?
[Chemical structure diagram of penicillamine]
- A boxed portion in the diagram highlights a specific functional group consisting of a carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group (OH).
**Options:**
A) alcohol
B) ketone
C) aldehyde
D) carboxylic acid
*Explanation of Chemical Structure Diagram:*
- The chemical structure displayed includes various elements and bonds.
- Highlighted in the box is a carbon atom double-bonded to an oxygen atom (C=O) and also bonded to a hydroxyl group (OH).
This is a typical representation of a carboxylic acid functional group.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff1fc3c1b-8869-498d-b8c7-2c621535c5fb%2F3c86dfd2-2e63-48ac-8532-ca6cdd7ff099%2F35s8k67_processed.jpeg&w=3840&q=75)
