QUESTION:
Each of the following compounds exhibits a \({ }^{1} \mathrm{H} \text { NMR }\) spectrum with only one signal. Deduce the structure of each compound:
(a) \(\mathrm{C}_{5} \mathrm{H}_{10}\)
(b) \(\mathrm{C}_{5} \mathrm{H}_{8} \mathrm{Cl}_{4}\)
(c) \(\mathrm{C}_{12} \mathrm{H}_{18}\)
ANSWER:Step 1 of 3
(a) The given compound \(\rm{C}_5\rm{H}_{10}\) giving only one signal in proton NMR is drawn below:
From the above-given structure, it is clear that all the ten hydrogens present in the chemical compound are chemically equivalent. Therefore, it has the same chemical environment, resulting in only a single signal in the \({ }^{1} \mathrm{H} \text { NMR }\) spectrum.
