Give the systematic name for ester $A$.
State what retention time means.
Calculate the percentage by mass of ester $D$ in the original mixture.
Complete Table 7.1 so that it shows the number of peaks in each NMR spectrum for esters $B$ and $C$.
Identify all of the esters from $A$, $B$, $C$ and $D$ that have at least one triplet peak in their proton ($^1\text{H}$) NMR spectrum.
Compound F, $\text{C}_6\text{H}_8\text{O}_3$, displays stereoisomerism and effervesces with $\text{Na}_2\text{CO}_3(\text{aq})$. Compound F reacts with alkaline $\text{I}_2(\text{aq})$ to give yellow precipitate G and compound H. Compound F reacts with $\text{LiAlH}_4$ to form compound J, $\text{C}_6\text{H}_{12}\text{O}_2$. Compound F reacts with $\text{SOCl}_2$ to form compound K, $\text{C}_6\text{H}_7\text{O}_2\text{Cl}$. Compound K reacts with propan-2-ol to form compound L. Draw the structures of compounds F, G, H, J, K and L in the boxes in Fig. 7.3.
