Web1H NMR, 13C NMR and infrared spectroscopy are used in organic chemistry to distinguish between compounds and to identify them. (a) Give the skeletal formula of the compound that is used as the standard when recording a 13C NMR spectrum. (1) (b) Four isomers of C 6 H 12 O 2, P, Q, R and S, shown in Figure 1, were analysed by 13C NMR spectrometry. WebSimilarly, the equatorial (alpha) anomeric proton resonates in addition down discipline (5.1 ppm) from the axial (beta) proton (4.5 ppm), making those anomer populations …

WebOct 19, 2024 · The N requires 2 additional bonds. Since there are 6 H remaining, either unsaturation or a multiple bond such as either C = N or C = O bond is still necessary. The broad singlet at 6.7 p p m suggests a single N − H proton, so we assume the N is part of the chain. Let's try an amide. WebMar 10, 2024 · For example, the C $^α$ has two neighbouring carbons so is split into a triplet and it also has one neighbouring hydrogen so those triplets are split into doublets making … WebFrom experimental design to data interpretation, ACD/Labs’ NMR predictors can significantly speed up your workflow.
