  3. Naming • __ ______ Ether • 1st is either the prefix of “Di-” or is the first alkyl group within the compound in alphabetical order. • 2nd is followed by the main alkyl group or the second alkyl group within alphabetical order. • All end with the word ether.

  4. Williamson Ether Synthesis + Na  + H—H Ethanol (l) Sodium (s) Sodium Ethoxide (s) Hydrogen gas (g) Note: This is occurs according to the SN2 reaction + + NaCl  Chloroethane (g) Sodium Ethoxide (s) Sodium Chloride (s) Diethyl Ether (l)

  5. SN2 reaction

  6. Williamson Ether Synthesis Cont. • Alkyl Halide- Halogen bonded to an alkyl group. • Nucleophile-a compound which donates a pair of electrons. • The nucleophile (lewis base) reacts which an alkyl halide. • After the reaction the products are a salt and an ether.
