Ether Properties You guessed it, ethers are extremely flammable! What are the products of ether combustion? Ethers have boiling points similar to alkanes of similar mass, but much lower than a corresponding alcohol. Why? Ethers have similar solubility in water as alcohols of the same mass. Why? Can hydrogen bond among others but not other ethers

Cyclic Ethers When the ether functional group is a member of a ring, we have cyclic ethers. Most have unique names and are used as the building blocks (both biological and synthetic chemistry) for larger compounds. These are the first heterocyclic organic compounds we’ll encounter. (Aka heterocylic rings) cycloalkene phenol cyclic ether O OH

Thiols and Thioethers Simply replace the oxygen atom with a sulfur atom. alcohol thiol ether thioether (sulfide) hydroxyl group sulfhydryl group Nomenclature addendum: Replace the –ol ending of the alcohol with –thiol . Replace the word ether with sulfide in the common name of thioethers. In the IUPAC name, the alkoxy ending becomes alkylthio . Physical properties: Thiol – lower boiling point than corresponding alcohol. Why? Very strong odor, usually unpleasant, but not all of them.

Disulfides Thiols can undergo oxidation to form disulfide bonds. This is a key component of protein structure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
