Homework Answers
the broad band at 2950 is due to hydroxy group stretching
the band at 1681 cm-1 is due to carbonyl group
the band at 3024 cm-1 is due to aromatic CH stretching
the band at 1631 cm-1 is due C=C stretching
the band at 1449 cm-1 is due to aromatic C=C stretching
therefore compound has -COOH group, aromatic group and alkene group
