Halogeno-compounds RX/ALQ/P.1 91(II)7.(b) When compound P is treated with potassium hydroxide in ethanol, two products Q , C 6 H 12 , and R , C 8 H 18 O , are obtained. C CH 3 CH 3 CH 2 CH 2 Cl CH 3 (i) Give the structure and the systematic names for Q . ( 2 marks ) 92(II)8.(c) Outline a reaction mechanism for the hydrolysis of 1-bromopropane with dilute aqueous potassium hydroxide and sketch a labelled energy profile diagram for the reaction. ( 4 marks ) 94(II)8.(b) A cyanoalkane is usually prepared by reacting the corresponding bromoalkane with aqueous potassium cyanide. (i) Using curly arrows to indicate electron pair shift, outline a mechanism of the reaction. (ii) Is it possible to use hydrogen cyanide instead of aqueous potassium cyanide to carry out this preparation ? Explain. ( 5 marks ) 95(II)8.(a) In an experiment, 46.3 g of 1-chlorobutane reacts with 30.0 g of sodium cyanide to give 35.2 g of pentanenitrile. (i)
