- If the imaginary replacement of either of two protons forms enantiomers, then those protons are said to be enantiotopic. The NMR is not a chiral probe, and it cannot distinguish between enantiotopic protons. They are seen to be “equivalent by NMR.” What other protons in cyclobutanol are enantiotopic?arrow_forwardCalculate the HDI, list important peaks from the IR spectrum and the functional group they correspond to, and draw the structure of the compoundarrow_forward1. In the empty boxes, indicate the maximum total number of possible peaks in the 1H NMR spectra of the compounds below. Label the unique types of H within the structures below as H1, H2, H3, etc. NOTE: keep in mind the molecule’s symmetry & use the “substitution test” approach of mentally substituting, one at a time, each H for Cl, to see how many monochloro isomers you would generate. This tells you how many different types of H are present, which equals the number of possible NMR peaksarrow_forward
