Explanation / Answer

1. Broad peaks 3400-2500 corresponds to O-H, peak near 1730 corresponds to C=O bond of carboxylic acid. Thus it is an carboxylic acid.

2. 3000 peak refers to sp3 CH3 , 1750 peak is for ester C=O. Thus it is an ester.

3. broad 3350-3180 peak refers to primary NH3 , 1680 peak is for amide C=O. thus it is an amide.
