Thanks! # Infrared (IR) Spectra Analysis for Compound Identification## OverviewThis exercise involves matching the given IR spectra with the most likely chemical compound from a provided list. Infrared spectroscopy is a powerful technique used to identify functional groups in molecules by measuring the vibrations of chemical bonds.### Spectral Data and CompoundsBelow are the IR spectra for four unknown compounds. Your task is to match each spectrum to one of the compounds listed on the right.### IR Spectra1. **First IR Spectrum:** - Prominent peaks can be observed that may indicate characteristic functional groups such as -NH, -OH, or carbonyl groups. - Broad peaks are typically indicative of O-H or N-H stretches found in alcohols or amines.2. **Second IR Spectrum:** - Multiple sharp peaks can be seen, indicating the presence of distinct functional groups. - Typically, carbonyl groups (C=O) show strong peaks around 1700 cm⁻¹, while C-H stretching can be observed around 2800-3000 cm⁻¹.3. **Third IR Spectrum:** - Additional detailed peaks could correlate with aromatic rings or complex hydrocarbons. - Aromatic C=C stretching is often present around 1600 cm⁻¹.### Compound List(a) \[ \text{NH} \quad \text{(Phenyl group)} \](b) \[ \text{CH}_3\text{CH}_2\text{CO}\](c) \[ \text{CH}_3\text{CH}_2\text{CH}_2\text{COH}\](d) \[ \text{CH}_3\text{CH}_2\text{CH}=\text{CHOH}\](e) \[ \text{HOCH}_2\text{CH}=\text{CHCH}_3\](f) \[ \text{OH} \quad \text{CH}_3\text{CH}_2\text{CHCH}_2\text{CH}_3\](g) \[ \text{O} \quad \text{C-CH}_2\text{CH}_2\text{CH}_2\text{CH}_3\](h) \[ \text{C}_6\text{H}_5\text{CH}_2\text{NH}_2

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼
