Explain why $\text{CDCl}_3$ is used as a solvent rather than $\text{CHCl}_3$.
Explain why TMS is added so that the small peak appears at chemical shift $\delta = 0$.
Compound E is hydrolysed by hot $\text{NaOH(aq)}$, producing only two organic products. One of these is ethanol. Name the functional group in compound E that is hydrolysed by hot $\text{NaOH(aq)}$.
Describe the splitting patterns of the peaks at $\delta = 1.4$ and $\delta = 4.3$, and explain them.
Each molecule of compound E contains five protons that produce the peaks between $\delta = 7.0$ and $\delta = 8.5$. Identify the functional group in compound E that contains these protons.
Give the structural formula for compound E.
In the mass spectrum of compound E, fragment ions appear at $m/e$ values of 29 and 77. Give the formulae of these fragment ions.
