(a)[1]
State the functional group found in ethanal, propanal and propanone.
(b)[2]
State a reagent and the matching observation that show F, G and H have the same functional group.
(c(i))[2]
Using Table 6.1, name the organic compounds in bottles F, G and H. F = \ldots G = \ldots H = \ldots
(c(ii))[1]
Identify the yellow precipitate that is formed when alkaline $\text{I}_2(\text{aq})$ is added to separate samples of F and G.
(c(iii))[1]
Compound J does not have the same functional group as F, G and H. It also gives a pale yellow precipitate with alkaline $\text{I}_2(\text{aq})$. Suggest the structure of compound J.
