Write balanced equations to show how ethyl ethanoate can be made from a) and acid halide and b) an acid anhydride.
Briefly outline the advantages and disadvantages of the different methods of making esters.
Explain how the haloform reaction can be used to distinguish between butan-2-one and propanal. Include a reaction mechanism for any reaction which occurs. If you have photographs of the iodoform experiment you may wish to include these.
HxCyOz + NaOH --> xH2O + NaxCyOz If 27.33ml of 0.0973M NaOH were used to titrate 0.328g of pure unknown carboxylic acid, determine the number of reactive H in a single molecule of the carboxylic acid.
