Use the ratio between the M and M+1 peaks to work out the number of carbon atoms in one molecule of T.
State the molecular formula of T.
The NMR spectrum of T shown below contains four absorptions. The signal at $1.8\,\text{ppm}$ is a multiplet, whereas the one at $2.5\,\text{ppm}$ is a singlet. Use this information together with your answer to a(ii) to deduce the structure of T.
Describe and explain which type of proton gives rise to each absorption.
The absorption at $1.8\,\text{ppm}$ is a multiplet, and the one at $2.5\,\text{ppm}$ is a singlet. State and explain the splitting patterns for the remaining absorptions at $0.9$ and $3.4\,\text{ppm}$.
Describe and explain how the NMR spectrum of T in $\text{D}_2\text{O}$ would differ from the spectrum shown.
