A little confused

I have already tried this problem and offered an explanation of why I think it should be. Please help me and if wrong could you offer some help or an explanation.

Deduce the structure and give the name.

I am pretty sure that I have figured out the problem, just one peice is stumping me. Do you think that you can help me figure out the structure and name. What I have may possibly be right. Question: Analyze the data given in each of the problems below, deduce the structure and give the name. A fishy-smelling liquid with elemental analysis of C=68.93%, H= 15.04% and N=16.08%. The Infrared Spectrum has a characteristic weak double peak at 3300 cm-1 (3.0 µm), and the 1H-NMR shows resonance peaks at 0.8(s,9), 1.1 (s,2), and 2.3 (s,2)ppm.... (see attachment for rest)

Tetrahydrofuran + Hydroiodic Acid

What product(s) would you expect to form when tetrahydrofuran is treated with excess hydroiodic acid (HI)?

Cleavage of Butyl Isopropyl Ether with HI

Write a suitable mechanism for the cleavage of butyl isopropyl ether with HI at 100 degrees C to form exclusively isopropyl alcohol and 1-iodobutane. Explain why butyl alcohol and isopropyl iodide are not formed in the reaction.
