Use the ratio of the M and M+1 peaks to calculate how many carbon atoms are present in one molecule of T.
State the molecular formula of T.
The NMR spectrum of T shown below contains four absorptions. The absorption 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 part (a)(ii) to deduce the structure of T.
Describe and explain which proton type gives rise to each absorption.
The absorption at $1.8\,\text{ppm}$ is a multiplet, while that at $2.5\,\text{ppm}$ is a singlet. State and explain the splitting patterns for the remaining absorptions at $0.9\,\text{ppm}$ and $3.4\,\text{ppm}$.
Describe and explain how the NMR spectrum of T in $\text{D}_2\text{O}$ would be different from the spectrum shown.
Describe and explain which type of proton is responsible for each of the absorptions.
The absorption at $1.8\,\text{ppm}$ is a multiplet and that at $2.5\,\text{ppm}$ is a singlet. State and explain the splitting patterns of the other absorptions, at $0.9\,\text{ppm}$ and $3.4\,\text{ppm}$.
