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 14:**
What product would you obtain from the reaction of hex-1-yne with BH₃, followed by H₂O₂, OH⁻?
**Options:**
- a.
- Structure: A three-carbon chain with an acetyl group (an oxygen double-bonded to a carbon) at the end of the chain.
- b.
- Structure: A four-carbon chain with a carbonyl (an oxygen double-bonded to a carbon) on the second carbon.
- c.
- Structure: A three-carbon chain with a hydroxyl group (OH) on the first carbon and another on the second carbon.
- d.
- Structure: A three-carbon chain with two hydroxyl groups (OH) attached to the second and third carbons.
Choices to select from:
