Please help with the last 3 questions

questions are

1. Use 1-2 key peaks to justify what compound(s) that you think are present.

2. Does this suggest that your reaction worked? Use 1 or two key IR peaks to justify your answer.

3. What does this IR data indicate about the purity of the product? Use 1 or two key IR peaks to justify your answer.

IR Spectrum for Product Obtained 1.1 1.0 0.9 0.8 0.7 0.6 Transmitance 0.5 0.4 0.3 0.2 0.1 3500 3000 2500 2000 1500 1000 500 Wavenumbers (cm-1) Use 1-2 key peaks to justify what compound(s) that you think are present. Saved Normal : B|I| X X = fx TX 1195 cm-1 indicates the presence of C-O stretching frequency. However, the peak is for ether groups. 1648-1676 cm-1 indicates the presence of C=C stretching frequency, this confirms that a benzene ring is present. 3100-3000cm-1 confirms the presence of C-H stretching frequency, a -CH3 group may be present.
