Which structure match IR

### Infrared Spectroscopy Analysis

#### IR Spectrum Graph

- **X-axis (Wavenumber, cm⁻¹):**
- Ranges from approximately 4000 cm⁻¹ on the left to 600 cm⁻¹ on the right.

- **Y-axis (Transmittance):**
- Scale from 0 to 100% transmittance.

- **Graph Description:**
- The IR spectrum shows several peaks and troughs across the wavenumber range.
- Notable absorption bands are observed around 1700 cm⁻¹, which typically indicate carbonyl (C=O) stretching vibrations.
- There is a broad region of absorption starting from approximately 3000 cm⁻¹, possibly indicating O-H or N-H stretching.

#### Chemical Structures

- **a.** Chemical structure featuring an aromatic ring with a methoxy group and an amino group.

- **b.** Chemical structure with an aromatic ring attached to an aldehyde functional group.

- **c.** Chemical structure of phthalic anhydride with characteristic cyclic anhydride bonds.

- **d.** Chemical structure of benzoic acid with an aromatic ring and a carboxylic acid group.

This IR spectrum can be analyzed to determine which functional groups are present in the unknown sample, based on the absorption bands corresponding to various chemical bonds.

Expert Solution

Step 1

Infrared spectroscopy provides useful information about the functional group present in a compound depending on the bond vibration.

IR spectra can not predict the whole structure of the molecule.
