Answer 1

Answer #1

IR:

3300 & 3350 cm-1, two bands, medium, N-H stretch in primary amine

2850 - 2950 cm-1, strong, sp3 C-h stretch

1600 cm-1, N-H bending in primary amine

1460 cm-1, medium sp3 C-H bending

HNMR & CNMR Assignment:

2.0 ppm, 2H, broad singlet represents free amino group - NH₂

1.6 ppm, 4H, pentet means symmetrical CH-CH₂-CH₃ group present

0.9 ppm, 6H, triplet, means symmetrical CH-CH₂-CH₃ group present

2.7 ppm, 1H, pentet small intensity means CH₃-CH₂-CH-CH₂-CH₃

HNMR CNMR HH N1 HSC HCL CH3 h | Assignment integration splitting Assignment shift | 6H triplet 10.0 pentet 30.0 우 54.0 우 pent
