Explanation / Answer

The given organic compound is an alcohol

3319.86 cm-1 is due to O-H stretching frequency, broad, strong signal

2923.31 cm-1 is due to sp3 alkyl C-H stretching frequency, strong signal

1378.73 -1467.03 cm-1 is due to sp3 alkyl C-H bending frequency, strong signal

1058.25-1189.12 cm-1 is due to C-O stretching frequency, medium signal

below 1000 cm-1 is fingerprint region, not much useful for prediction of functional groups, just only rocking, twisting, scissoring, wagging vibrational frequencies. Difficult to predict.
