Answer 1

Identification of compound by spectral data

IR

3280 cm-1 for N-H stretch

1653 cm-1 for C=C stretch

1H NMR

1.05 ppm (t, 3H) for CH3 next to CH2

1.85 ppm (s, 3H) for CH3 on quaternary alkenic C

2.6 ppm (q, 2H) for CH2 between CH3 and NH

3.08 ppm (s, 2H) for CH2 between NH and alkenic C

4.8 ppm (d, 2H) for terminal alkenic CH2
