This answer is
not correct. You have incorrectly identified the functional group as an amine
due to the strong broad absorption at 3400 cm-1. This absorption is
too strong for an amine and a primary amine should show 2 bands in this region.
The PMR spectrum is correct for a 2-propyl group but the labile hydrogen atoms
would absorb in the region from 0.5 to 3 ppm.
