2 A white solid, D, is formed when ethanoyl chloride is added to a concentrated solution of ammonia. The molecular formula of D is C2H5ON. When solid D is heated with excess aqueous sodium hydroxide solution, ammonia gas is given off and a solution, E, is formed. (a) Ammonia has a distinctive smell. Give two other tests, each of a different type, which could be used to show the presence of ammonia. Give the result of each test. (3) Test 1Test 2(b) Excess dilute sulfuric acid is added to solution E and an organic liquid, F, is distilled from the mixture. (i) Draw a labelled diagram of the apparatus used for this distillation. (2) *P45046A0416*<br /> (ii) Addition of pure liquid F to aqueous sodium carbonate gives effervescence. Identify liquid F by name or formula. (1)(c) (i) Give the name and displayed formula of solid D.
