(a(i))
The table below contains some oxygen-containing organic compounds together with some familiar laboratory reagents. Fill in the table as completely as possible. If you judge that no reaction takes place, enter ‘no reaction’ in the box for the structural formula(e).
(a(ii))[10]
In (i), some of the reactions show a colour change. Complete the table below for any of those reactions, giving the reaction letter and the colour change.
(b(i))
Draw the structural formula for the organic compound that is produced when $\text{HOCH}_2\text{CH}_2\text{CHO}$ reacts with 2,4-dinitrophenylhydrazine reagent.
(b(ii))[2]
Suggest the colour shown by the organic product.
