Exam questions on Alcohols and their reactions

1. A technician is given a colourless liquid labelled as propan-2-ol, a solvent used in cleaning products, and wants to confirm that it is an alcohol and then convert it into a halogenoalkane.
   The technician adds phosphorus(V) chloride to a sample of the liquid. State what is observed and write the equation for the reaction with propan-2-ol.2 marks
2. Butan-1-ol, C₄H₉OH, is being investigated as a possible biofuel. Relative atomic masses: C = 12.0, H = 1.0, O = 16.0.
   Calculate the mass of carbon dioxide formed when 3.70 g of butan-1-ol burns completely in excess oxygen.2 marks
3. A chemist makes two different compounds from ethanol, one by a halogenation reaction and one by an elimination reaction, in separate experiments.
   Ethanol is converted into bromoethane using potassium bromide and 50% concentrated sulfuric acid. State the conditions, show how the reactive reagent is formed, and write the equation for the reaction of ethanol with that reagent.3 marks
