Answers available below

PMT Some reactions involving ethanol are shown. reaction 1 reaction 2 CH3CH2OH distil with Cr2O7 2 + H+ CH3CH2Cl heat with NaOH in ethanol (a) (i) Give an equation for reaction 2 including the reagent needed for the conversion.[2] (ii) State the reagent and conditions required for reaction 1.[2] (b) (i) Identify the organic product X.[1] (ii) Nitric acid is added to the products of reaction of CH3CH2Cl with NaOH in ethanol. Silver nitrate solution is then added to this mixture. State what you would observe.[1] (iii) Write an ionic equation, including state symbols, for the reaction responsible for the observation in (ii).[1] (c) (i) Identify the organic product Y which is distilled out of the reaction mixture.[1] (ii) Explain, in terms of the properties of and intermolecular forces in CH3CH2OH and Y, why the chosen conditions for the reaction ensure that Y is the product.[3] [Total: 11] Permission to reproduce items where third-party owned material protected by copyright is included has been sought and cleared where possible.
