ETHER Maddy Thorn Sydney Yocum Jason Tutchton Period 1 Hinkson Basic Structure Ether has two carbon bonds to an oxygen atom Has a pair of alkyl or atomic groups attached to a linking oxygen atom. Functional group is ROR Have primary, secondary, and tertiary structures Characteristics Melting point of 116.3° C Boiling point of 34.6° C Molecular weight of 750 Colorless No strong odor Primarily a liquid Nomenclature All are named as alkoxy derivatives of alkanes Always named in alphabetical order Can be symmetrical or unsymmetrical Example: diethyl ether is symmetrical Ethyl methyl ether is unsymmetrical Mechanisms Example 1: synthesis of ethers is used to make sterically hindered symmetrical ethers Mechanisms ctnd. Williamson reaction Method: an acid-base • SN2 reaction: when ethers are treated with acid, they can give off strong alcohols and halides. Examples Ethylene glycol Dimethyl ether Diethyl ether Polyethylene glycol Cycloprenthyl methyl ether Real World Importance Ethyl Ether First used in anesthetics for surgery Used to remove gum Also used as a muscle relaxer Multiple Choice Questions 1.
