Match spectrum A to one of the following molecules: m-toluidine, m-tolualdehyde, 3-methylpyridine, m-toluic acid, and m-cresol.
Understand the Problem
The question presents a set of organic molecules and an IR spectrum (Spectrum A). The task is to identify which molecule corresponds to the given spectrum. This requires understanding the relationship between functional groups and characteristic IR absorption bands.
Answer
m-tolualdehyde
Spectrum A corresponds to m-tolualdehyde.
Answer for screen readers
Spectrum A corresponds to m-tolualdehyde.
More Information
The key feature in the IR spectrum A is the strong absorption band around 1700 cm-1, which is characteristic of a carbonyl group (C=O) in aldehydes. m-tolualdehyde matches this.
Tips
When matching IR spectra to compounds, focus on identifying key functional groups from characteristic peaks.
