A type of them can be used to make inorganic salts soluble in nonpolar organic solvents. That type can exist in an 18-member ring around potassium, a 15-member ring around sodium, or a 12-member ring around lithium. Essential to the formation of Grignard reagents, they can be created by bimolecular dehydration of alcohol or the Williamson synthesis and sometimes exist in the "crown" form. For 10 points, name this organic compound containing a bond between an oxygen atom and two alkyl groups, whose diethyl form was once a common anesthetic.
