Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).
IR Spectrum Of Cyclohexanone
It is the analysis of the structure of cyclohexaone using IR data interpretation.
IR Spectrum Of Anisole
Interpretation of anisole using IR spectrum obtained from IR analysis.
IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
![The image presents a two-part question asking to predict the product of chemical reactions.
1) **First Reaction:**
- **Reactants:**
- A cyclohexanone molecule.
- A pyrrolidine molecule (a five-membered ring with an NH2 group).
- Sulfuric acid (H2SO4).
- **Process:**
- The reaction typically involves the formation of an imine intermediate where the amine group from pyrrolidine attacks the carbonyl carbon of the cyclohexanone, with sulfuric acid acting as a catalyst.
2) **Second Reaction:**
- **Reactants:**
- The same initial reactants as in the first reaction (cyclohexanone, pyrrolidine, H2SO4).
- Sodium borohydride cyanoborohydride (NaBH3CN).
- **Process:**
- After the formation of the imine intermediate, sodium cyanoborohydride is used for reductive amination, resulting in the formation of a secondary amine.
These reactions illustrate the concept of reductive amination, a method used to introduce or modify amine functionality in organic molecules. The diagram does not include visual data like graphs but focuses on the structural formula of the reactants and reagents.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffbc57344-aee0-4c7a-83a5-ce0e8c0e16d3%2F430c0470-ab79-49ed-a0e2-c95a806590b5%2Fg34799f_processed.jpeg&w=3840&q=75)
