L04 - Understand the reactions of the alcohols.
AC 4.1 State the reaction conditions and write equations for the oxidation of alcohols.
AC 4.2 State the reaction conditions and write equations for the dehydration of alcohols.
AC 4.3 Draw and explain mechanisms for the formation of haloalkanes through the nucleophilic substitution reactions of alcohols.
1 a) Draw displayed formulae and name at least one primary, secondary and tertiary alcohol.
b) Alcohols can be oxidised using acidified potassium dichromate.
2. Explain the term dehydration', describe the reaction conditions needed and the products formed from the dehydration of alcohols. Write an equation for the dehydration of propan-1- ol to from propene
3. explain why the dehydration of alcohols provides a way of manufacturing polymers such as polyethene without using fossil fuels.
4. haloalkanes can be made through nucleophilic substitution reactions of alcohols.
a) define the terms 'nucleophile' and 'substitution reaction'
b) draw the sn2 mechanism for the formation of bromoethane from ethanol.
c) write an equation for the preparation of 2-chlorobutane from an alcohol
