Question

Identify the following compounds based on their spectroscopic data (draw the structure). Explain briefly how you arrived at your answer. That is, show how you have interpreted the data provided CH13N 'H NMR: 8 1.0 ppm, 1, 3H 1.2 ppm, s, 2H (exchanges with D:0) 1.9 ppm, quintet, 2H 3.9 ppm, t, 1H 7.2 ppm, broad multiplet, 5H write the HDI value in the box below Enter your answer here

Answer 1

Answer - The Cg His N. given moleculer Gormula is Degree CGHIGN a unsaturation molecular formley modified formula cntantz Clolaa I . Degree of unsaturation = 4 I NMR. 11.0ppm t 34 2. 2 ppm s 24 c exchanges with p2o) 3. 1-4 Porn iИ 4 4-2 ppm brad multiplet, su

oppm This + 34. indicate that CH3 - CH2 34 t 2 1.2 ppm S 24 cexchangs with D20) R - NH2 1.2 s 2H 3 1.9 ppm - quintet 24. This indicate that - CH2 - CH3 2n quientate 4. 3.9 ppm t 1H. indicate This - CH - 42 39 in triplet
