Explanation / Answer

Identification of compound

IR shows,

peaks between 2850-2950 cm-1 due to aliphatic C-H streching

1466 cm-1 peak for ether C-O stretch

NMR shows,

peaks between 0.5 to 1.5 ppm all in the aliphatic region protons.

peak at 3.5 could be for protons on carbon next to Oxygen of ether.

Thus the unknown possibly is an ether compound with aliphatic structure.
