Task

Three isomers A, B and C of composition C₃H₈O are given. A and B release hydrogen with sodium; C does not react with sodium. Hot copper(II) oxide converts A into a substance that gives the silver-mirror test and B into one that does not. Heating A or B with concentrated sulfuric acid at 170 °C gives the same gaseous product. 1) Write the structural formulas of A, B and C, name them and state the types of isomerism. 2) Write the oxidation of A and B by copper(II) oxide, name the products, and write the silver-mirror reaction of the oxidation product of A. 3) Write equations for intermolecular and intramolecular dehydration of A and B (with conditions). 4) Write the reactions of A and B with sodium and explain from its structure why C does not react with sodium. No calculations are required: for each part give the reaction equations (with structural formulas), conditions, names of substances and the necessary explanations.
