Ether naming and introduction | Organic chemistry | Khan Academy

TL;DR

This video explains the common and IUPAC names for ethers and discusses their properties as solvents.

Transcript

We've already touched on ethers in several videos. They've been our useful aprotic solvent in several of our reactions. But I thought it was about time that we actually devoted a video or two to ethers. And like all things that we've done in organic chemistry, a good way to familiarize ourselves with the molecules and how they look, is to actually ... Read More

Key Insights

• 🤲 Naming ethers involves identifying the carbon groups attached to the oxygen atom and using either common or IUPAC naming conventions.
• 🤲 Common names are often preferred for ethers due to their simplicity and practicality.
• 🤲 Ethers are commonly used as solvents in organic chemistry reactions, especially when an aprotic solvent is required.
• 🫠 Ethers have lower melting and boiling points compared to substances with hydrogen bonding due to the absence of such bonding in the molecule.

Questions & Answers

Q: What is the common name for diethyl ether?

The common name for diethyl ether is "diethyl ether," which indicates the presence of an oxygen atom between two ethyl groups.

Q: How is the IUPAC name for diethyl ether different from the common name?

The IUPAC name for diethyl ether is "1-ethoxyethane," which indicates that the oxygen atom is attached to the first carbon of the ethane chain, with an ethoxy group extending from it.

Q: Why are common names more commonly used for naming ethers?

Common names are more commonly used for ethers because they are simpler and more intuitive. They directly describe the two carbon groups attached to the oxygen atom, making it easier to understand the structure of the molecule.

Q: Why do ethers make good solvents?

Ethers make good solvents, particularly as aprotic solvents, because they do not have hydrogen atoms directly bonded to the oxygen atom. This prevents the formation of hydrogen bonding and makes ethers less reactive and more suitable for certain reactions.

Summary & Key Takeaways

• The video focuses on naming ethers, using both common and IUPAC names.

• The common name for an ether is based on the names of the two carbon groups attached to the oxygen atom, while the IUPAC name follows the same naming conventions as other organic molecules.

• Ethers are commonly used as solvents in organic chemistry reactions due to their unreactive nature and aprotic properties.
