Read moreAlcohols: The Conjugate Acid Is A Better Leaving Group, and The Conjugate Base Is A Better Nucleophile In the last post we explored some of the properties and
Read moreAcid-Base Reactions Of Alcohols Alcohols are mild acids. Typical aliphatic (i.e. “alkyl”) alcohols such as ethanol, isopropanol, and t-butanol have a pKa of about 16-18, making
Read moreThe Williamson Ether Synthesis In the Williamson Ether Synthesis, an alkyl halide (or sulfonate, such as a tosylate or mesylate) undergoes nucleophilic substitution (SN2) by an alkoxide to give an ether.

Read moreHow To Make Ethers With Alcohols And Acid Symmetrical ethers can be made from the acid-catalyzed dehydration of primary alcohols. A classic example is the
Read moreAcidic Cleavage of Ethers Can Proceed Through an SN2 or SN1 Mechanism, Depending On The Structure Ethers do not undergo very many reactions. One key
Read moreProperties and Synthesis of Epoxides Epoxides (oxiranes) are cyclic ethers that have unusually high reactivity due to ring strain (about 13 kcal/mol). The 3-membered ring
Read moreOpening Epoxides With Aqueous Acid Epoxides can undergo ring-opening with nucleophiles under acidic conditions. In this reaction, the epoxide oxygen is protonated first, making it
Read moreRing-opening of epoxides with basic nucleophiles Epoxides are cyclic ethers with considerable ring strain (about 13 kcal/mol) Epoxides undergo reaction with nucleophiles under basic conditions
