Propose a structure for an amine of formula \(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{~N}\), which does not liberate a gas when treated with \(\mathrm{NaNO}_{2}\) and \(\mathrm{HCl}\), and has IR absorptions at \(917 \mathrm{~cm}^{-1}, 990 \mathrm{~cm}^{-1}\), and \(1640 \mathrm{~cm}^{-1}\), as well as an \(\mathrm{N}-\mathrm{H}\) absorption at \(3300 \mathrm{~cm}^{-1}\). The \({ }^{13} \mathrm{C}\) NMR spectrum is as follows: \(\delta 36.0, \delta 54.4, \delta 115.8, \delta 136.7\).

Propose a structure for this H NMR and C13 NMR spectroscopy.
Mass Spectrum (not shown): \([\mathrm{M}]=193(100 \%) \mathrm{m} / 2\)IR Spectrum (not shown): \(3300(\mathrm{~m}), 3200(\mathrm{~m}) 3060,2985,1725,1600,1495 \mathrm{~cm}^{-1}\) (all listed are strong (s) unless otherwise indicated)- \(\mathrm{H}\) NMR Spectrum \(\left(400 \mathrm{MHz}, \mathrm{CDCl}_{3}, 25^{\circ} \mathrm{C}\right)\)The answer is not this: Pretty sure the formula is C11H15NO2.

Problem #23: When compound X (C,H,Br) is reacted with sodium cyanide (NaCN) forms compound Y (C,H,N). Compound Y, upon reduction with H over a Ni catalyst, yields compound Z (C,HIN. The 'H NMR spectrum of X gives two signals, a multiplet at δ = 7.3 ppm (5H) and a singlet at δ 4.25 ppm (2H). The 'H NMR spectrum of Y is similar to that of X in that it shows a multiplet at ö-7.3 ppm (5H) and a singlet...
