Ist spectra from TOP
the band at around 3300 cm-1 is due to the hydroxy group
the band between 2850 - 2950 cm-1 is due to aliphatic CH stretching
based on the above analysis the structure of the compound must be aliphatic alcohol
IInd spectra from TOP
the band at around 2850 - 2950 cm-1 is due to aliphatic CH stretching
the band at around 1700 cm-1 is due to the carbonyl group
the band at around 1200 cm-1 is due to C-O stretching
based on the above analysis the structure of the compound must be ester
IIIrd spectra from top
the strong band at around 3025 cm-1 is due to aromatic CH stretching
the band at around 2850 - 2950 cm-1 is due to aliphatic CH stretching
the band at around 1450 cm-1 might be due to aromatic C=C stretching
therefore compound must be an aromatic compound
