Primary and secondary alcohols can be oxidised by heating with a mixture of potassium dichromate(VI)and dilute sulfuric(VI) acid. •A primary alcohol can be oxidised to two different products, depending on the conditions used. •A secondary alcohol forms one product when oxidised. Tertiary alcohols cannot be oxidised. a)What is the formula of potassium dichromate(VI)? b)Using a primary alcohol of your choice as an example: i)give the displayed formulae of the two products it could be oxidised to ii) state the conditions needed to give each product iii) state which homologous series each product belongs to iv) write a balanced chemical equation for each reaction (the convention [O] may be used for the oxidising agent). d) Why are tertiary alcohols resistant to oxidation?

a)What is the formula of potassium dichromate(VI)?
b)Using a primary alcohol of your choice as an example:
i)give the displayed formulae of the two products it could be oxidised to
ii) state the conditions needed to give each product
iii) state which homologous series each product belongs to
iv) write a balanced chemical equation for each reaction (the convention [O] may be used for the
oxidising agent).
