4. Aldehydes, in particular 3,6-Nonadienal, are a dominant product of the oxidation of linolenic acid. Show the steps in the formation of the aldehyde from the auto-oxidation of linolenic acid. Note that the major hydroperoxides formed by autoxidation of linolenic acid are 9-ROOH, 12-ROOH, 13-ROOH, 16- ROOH and 16-ROOH.
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.

![**Formation of Aldehydes from Linolenic Acid**
Aldehydes, particularly 3,6-Nonadienal, are prominent products from the oxidation of linolenic acid. The following highlights the steps involved in forming these aldehydes through the auto-oxidation process of linolenic acid. It is important to note that the major hydroperoxides formed during this process are 9-ROOH, 12-ROOH, 13-ROOH, 16-ROOH, and 16-ROOH.
**Chemical Diagram Explanation**
The diagram shows the molecular structure of linolenic acid, with specific bonds and atoms labeled:
- **HO:** Represents the hydroxyl group at the beginning of the carbon chain.
- The carbon chain contains multiple double bonds, indicated by the marked positions 9, 12, and 15 (in blue), corresponding to the location of double bonds within the carbon chain.
- Positions 3, 6, 9, and 12 are indicated in red, showing areas of interest for autoxidation and hydroperoxide formation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd7323f76-5a9c-46b6-9930-86cefe6607d1%2F49e6147b-4dbc-400f-b15e-690417eccdad%2Fibztpz_processed.png&w=3840&q=75)
