Unformatted text preview: R-X AgNO 3 ethanol AgX + R + Vinylic and aryl halides do not readily react. X and R 2 C=CR X AgNO 3 ethanol no reaction Silver Nitrate in Aqueous Ammonia A solution of AgNO 3 in aqueous ammonia produces the complex Ag(NH 3 ) 2 OH, a complex of silver (I). Terminal alkynes (pKa ~ 25) are deprotonated and yield an insoluble silver alkynide: RC C-H + Ag(NH 3 ) 2 + + HO-RC C-Ag + H 2 O + 2NH 3 insoluble black precipitate Silver alkynides dissolve in nitric acid but silver halides do not. Quiz 8.016 An organic compound is soluble in cold, conc. sulfuric acid, but does not decolorize a solution of Br 2 in CCl 4 . Which structure below is consistent with these observations? OH Cl...
