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 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 reactant is a cyclohexene with two methyl groups: one methyl group is attached at the fourth position with a wedged bond, and the other methyl group is attached at the first position with a plain bond.
- The reaction involves ozonolysis with reagents:
1) O₃
2) (CH₃)₂S
**Answer Options:**
1. **Option A:**
- Produces a linear carbon chain with six carbon atoms.
- The compound contains two carbonyl groups (C=O).
- The first carbonyl group is at the second carbon, attached to a methyl group at the stereocenter.
- The second carbonyl group is at the sixth carbon.
2. **Option B:**
- Produces a linear carbon chain with six carbon atoms.
- Contains two carbonyl groups.
- The first carbonyl group is at the first carbon, attached to a hydrogen at the stereocenter.
- The second carbonyl group is at the fifth carbon, attached to a methyl group at the stereocenter.
3. **Option C:**
- Produces a linear carbon chain with six carbon atoms.
- Contains two carbonyl groups.
- The first carbonyl group is at the first carbon, attached to a hydrogen at the stereocenter.
- The second carbonyl group is at the sixth carbon, attached to a methyl group at the stereocenter.
4. **Option D:**
- Produces a linear carbon chain with five carbon atoms.
- Contains two carbonyl groups.
- The first carbonyl group is at the second carbon, attached to a methyl group at the stereocenter.
- The second carbonyl group is at the fifth carbon.
**Analysis:**
The reaction is ozonolysis followed by reductive workup. Ozonolysis of alkenes typically cleaves the double bond and forms two carbonyl compounds. When a reductive workup (e.g., with dimethyl sulfide) is used, it prevents further oxidation to carboxylic acids.
