The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). This reaction was developed by Alexander Williamson in 1850. Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an SN2 reaction. This reaction is important in the history of organic chemistry because it helped prove the struc… WebExpert Answer. 3. (6 points) Two students set out to synthesize diethyl ether from ethanol. Both chose to utilize the bimolecular dehydration synthetic procedure (mixing the alcohol with a strong acid at "reasonably" low temperatures (∼ 140∘C) ). The students were graded on the yield of diethyl ether from their syntheses.
