1 Structure and physical properties alcohols Recap the structure of alcohols and introduce primary, secondary and tertiary alcohols. Use data to analyse and compare the boiling points of alkanes, alkenes and alcohols, explain this in terms of hydrogen bonding use IUPAC rules to name alcohols and identify primary, secondary and tertiary alcohols interpret data on boiling points of the homologous series studied so far explain how hydrogen form in alcohols and the impact this has on their properties 3.3.5.1 Ethanol production Alcohols are produced industrially by hydration of alkenes in the presence of an acid catalyst. Ethanol is produced industrially by fermentation of glucose. The conditions for this process. Ethanol produced industrially by fermentation is separated by fractional distillation and can then be used as a biofuel. Students should be able to: explain the meaning of the term biofuel; justify the conditions used in the production of ethanol by fermentation of glucose; write equations to support the statement that ethanol produced by fermentation is a carbon neutral fuel and give reasons why this statement is not valid; outline the mechanism for the formation of an alcohol by the reaction of an alkene with steam in the presence of an acid catalyst; discuss the environmental (including ethical) issues linked to decision making about biofuel use. AT a, d and k PS 1.2: Students produce ethanol by fermentation, followed by purification by fractional distillation. 15.1 2 Industrial manufacture of ethanol Introduce the commercial production of ethanol from the hydration of ethane. Discuss the reasons for the reaction conditions and outline the mechanism for the reaction describe how alcohols are produced industrially by the hydration of ethene use le Chatelier’s principle to explain the conditions used for its manufacture outline the mechanism for the reaction between ethene and steam 15.2 3 Ethanol by fermentation out a practical to produce ethanol by fermentation. Discuss the features and uses of the apparatus and reagents used. Discuss the use of ethanol as a biofuel and the ethical implications arising from its use. explain the term biofuel and the ethical issues associated to their use explain the conditions and processes required for the production of ethanol by fermentation use equations to support the statement that ethanol produced by fermentation is a carbon neutral fuel and explain why this statement is not valid 15.2
