Seventy-five cc. of ethyl bromide and 50 cc. of strong ammonia (sp. gr. 0.88) were taken in a 750 cc. thick glass flask, sufficient ... 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… dejan matić glumac
