Question
Assign each of the spectra to the correct structure. Each Spectra only identifies to one of the molecules. Provide a reasonable explanantion of how you came to the assignment you made. At the minimum that will mean identifying a specific absoprtion band which identifies each characterisitic functional group of the molecule chosen.
IR Molecules Molecule 1 Molecule 2 NH2 Molecule 3 Molecule 4 CH H2C CH3 CH 0 Molecule 5 Molecule 6 OH HO Molecule 7 Molecule 8 OH NH2 ÖCH3 CH3 Molecule 9 Molecule 10 OHExplanation / Answer
Spectrum A (Molecule 6: 3500 to 3000 cm-1 hydroxy stretch, 1740 cm-1 carbonyl stretch).
Spectrum B ( Molecule 8: 3300 cm-1 two peaks and 1600 cm-1 C=C stretch. Therefore the compound is p-methyl aniline).
Spectrum C (Molecule 3: 2900 cm-1 sp3 C-H stretch and 1738 cm-1 carbonyl stretch).
Spectrum D (Molecule 10: 3100 cm-1 sp2 C-H stretch, 2900 cm-1 sp3 C-H stretch and 1600 cm-1 C=C stretch).
Spectrum E (Molecule 2 : 2900 cm-1 sp3 C-H stretch, 2800 cm-1, 2700 cm-1 two peaks indicates aldehyde C-H stretch and 1725 cm-1 carbonyl stretch.
Spectrum F (Molecule 9 : 3500 to 3000 cm-1 hydroxy stretch and 1700 cm-1 carbonyl stretch).
Spectrum G (Molecule 4 : 3300 cm-1 sp C-H stretch, 2200 cm-1 C triple bond C stretch, 1600 cm-1 C=C stretch).
Spectrum H (Molecule 1 : 3300 cm-1 two peaks indicates primary amine and 1700 cm-1 carbonyl stretch).
Spectrum I (Molecule 5 ; 3500 to 3000 cm-1 hydroxy stretch and 1710 cm-1 carbonyl stretch).
Spectrum J (Molecule 7: 3100 cm-1 sp2 C-H stretch, 1600 cm-1 C=C stretch).
