Atoms, molecules and stoichiometry — practice question

A number of organic compounds, such as alcohols, carbonyl compounds, carboxylic acids and esters, include oxygen.
(a(i))

Fill in the table as completely as possible. If you believe no reaction takes place, enter 'no reaction' in the box for the structural formula(e).

(a(ii))[10]

A colour change occurs in some of the reactions in part (a)(i). For any that do, complete the table below by giving the reaction letter and describing the colour change.

(b(i))

Draw the structural formula of the organic compound produced when $\text{HOCH}_2\text{CH}_2\text{CHO}$ is reacted with 2,4-dinitrophenylhydrazine reagent.

(b(ii))[2]

Suggest the colour shown by the organic product.
