- Reaction of butanenitrile (CH3CH2CH2CN) with methylmagnesium bromide (CH3MgBr), followed by treatment with aqueous acid, forms compound G. G has a molecular ion in its mass spectrum at m/z = 86 and a base peak at m/z = 43. G exhibits a strong absorption in its IR spectrum at 1721 cm−1 and has the 1H NMR spectrum given below. What is the structure of G?arrow_forwardPropose a structure consistent with each set of spectral data: a.

- Propose a structure consistent with each set of data. C10H14: IR absorptions at 3150–2850, 1600, and 1500 cm−1arrow_forward(a) The 'H-NMR spectrum of cyclobutanone shows two signals - signal A at 3.00 ppm and signal B at 1.95 ppm. Give the multiplicity of each signal. cyclobutanone (b) When cyclobutanone is treated with D20 and NaOD, the only signal observable in the 1H-NMR is a singlet at 2.00 ppm. Explain why this is the case. [Note: Deuterium atoms do not display signals in the TH-NMR spectrum]arrow_forward15. Compound C has a molecular weight of 94.54 and the 1H-NMR spectrum shows four signals - a triplet at 3.81 ppm, a triplet at 3.63 ppm, a singlet at 2.19 ppm, and a triplet of triplets at 2.02 ppm.

- Compound C has a molecular ion in its mass spectrum at 146 and a prominent absorption in its IR spectrum at 1762 cm-1. C shows the following 1H NMR spectral data: 1.47 (doublet, 3 H), 2.07 (singlet, 6 H), and 6.84 (quartet, 1 H) ppm. What is the structure of C?arrow_forwardplease help with this question. thank you. Given that compound X has a molecular formula of C6H10O2, gave three peaks in its 13C NMR spectrum (14, 63 and 158 ppm) and two peaks in its 1H NMR spectrum (1.4 ppm, triplet and 4.3 ppm, quartet), provide a structure for compound X and briefly explain.arrow_forwardcompound with the molecular formula C7H9N exhibits IR bands at 3450 cm-1 (medium, doublet), and 855 cm-1 (strong) and shows the following major mass spectral signals (m/z): 106 (base); 107 (M+, about 70% of base), 91 (40% of base), and 77 (about 20% of base).
