Concept explainers

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

Question

2) Propose a structure for C4H100. The 1H NMR data is as follows [splitting, chemical shift
(integration)]: singlet, 8 1.28 (9H) and singlet, 8 1.35 (1H). Look carefully at what the integration and
splitting tell you.
