The compound that exhibits sharp bands at 3300 and 2150 cm-1 in IR spectrum is,1-butyne2-butynebutylaminebutyronitrile

The compound that exhibits sharp bands at 3300 and 2150 cm-1 in the IR spectrum is butyronitrile.

Here's why:

1. The sharp band at 3300 cm-1 is indicative of a C-H stretch in a nitrile group (-C≡N).

2. The sharp band at 2150 cm-1 is indicative of a C≡N stretch in a nitrile group.

3. 1-butyne and 2-butyne are alkynes and would show a sharp band near 2150 cm-1 for the C≡C stretch, but not near 3300 cm-1.

4. Butylamine would show a band near 3300 cm-1 for the N-H stretch, but not near 2150 cm-1.

5. Butyronitrile, however, contains a nitrile group, and would show bands near both 3300 cm-1 (for the C-H stretch) and 2150 cm-1 (for the C≡N stretch). Therefore, the compound is butyronitrile.
