Draw the skeletal formulae for A, B and C.
Name the type of structural isomerism shown by A and B.
State the observation when a sample of A is warmed with Tollens’ reagent.
Give the structures of D, E and F, showing the two stereoisomers of E and labelling the stereoisomerism present.
Identify the gas formed when each of these isomers reacts with sodium metal.
Give the equation for the reaction between $\text{C}_3\text{H}_6\text{O}$ and acidified potassium dichromate(VI), using $[\text{O}]$ where suitable.
Give the equation for the reaction between $\text{C}_3\text{H}_6\text{O}$ and sodium tetrahydroborate, $\text{NaBH}_4$, using $[\text{H}]$ where needed.
Another compound, G, $\text{C}_3\text{H}_6\text{O}$, has the same functional group as A. Give equations for the reactions of G with both acidified potassium dichromate(VI) and sodium tetrahydroborate, $\text{NaBH}_4$, using [O] or [H] as appropriate.
