Based on the spectra you located, does your molecule have a carbonyl? If so, what functional group is it a part of (carboxylic acid, ketone, aldehyde, ester, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a carbonyl? Does your molecule have either an –O-H or –N-H bond? If so, what functional group is it a part of (carboxylic acid, alcohol, amine, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what are the approximate frequency ranges for an –O-H and an –N-H bond? Does your molecule have either an alkyne or nitrile functional group? If so, which functional group is it and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a triple bond?

Transcribed Image Text:**Title: Infrared Spectrum of Benzoic Acid, Sodium Salt**
**Description:**
This graph represents the Infrared (IR) Spectrum of Benzoic Acid, Sodium Salt. The x-axis is labeled "Wavenumbers (cm⁻¹)" and spans from 3750 to 500 cm⁻¹. The y-axis is labeled "Transmittance" ranging from 0.0 to 1.2.
**Graph Details:**
- **Transmittance Peaks:** The graph shows various peaks indicating different levels of transmittance across the spectrum. Peaks in an IR spectrum correspond to the absorption of IR light by molecular bonds at specific wavenumbers, which are indicative of certain functional groups.
- **Key Regions:**
- **Above 3200 cm⁻¹:** The spectrum remains relatively flat, indicating minimal absorption in this region.
- **Around 1750 cm⁻¹ and 1600 cm⁻¹:** Significant drops in transmittance occur, which are typical of carbonyl (C=O) stretches often seen in carboxylic acids and their salts.
- **Below 1000 cm⁻¹:** Several sharp peaks are present, which may correspond to bending vibrations and other bending modes of various bonds.
**Interpretation:**
The IR spectrum highlights the characteristic absorption bands of the sodium salt derivative of benzoic acid, which helps in identifying functional groups and verifying compound structure. It can be used to determine the presence of specific chemical bonds based on known absorption characteristics.
Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
