The scientist has an IR spectrometer in her lab. She acquires an IR spectrum of compound X and finds a relatively weak intensity absorption at ~2100 cm-1 and some medium to strong absorptions in the 2850~2960 cm-1 region plus a strong absorption at 3300 cm-1. Identify the type of bonds that are represented by these signals (be very specific) and hence show the most likely structure or compound X.
