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).
![## Reaction: Cyclopentene with Diiodomethane
### Problem Statement
- **Instruction:** Draw the structure of the major organic product of the reaction below.
### Reactants and Conditions
- **Starting Material 1:**
- Cyclopentane ring with an ethylene group (\( \text{CH} = \text{CH}_2 \))
- **Starting Material 2:**
- Diiodomethane (\( \text{CH}_2\text{I}_2 \))
- **Reagent and Conditions:**
- Zinc-Copper couple (Zn(Cu))
- Ether as solvent
### Diagram Explanation:
The diagram illustrates the reaction between cyclopentene and diiodomethane in the presence of a zinc-copper couple and ether as the solvent.
### Expected Major Organic Product
This reaction typically results in the formation of a cyclopropane ring through the Simmons-Smith reaction. Diiodomethane, in the presence of the zinc-copper couple, forms a carbenoid intermediate. This intermediate adds to the double bond of cyclopentene, resulting in a cyclopropane ring fused to the cyclopentane ring.
### Detailed Reaction Mechanism (Explanation):
1. **Formation of Carbenoid Intermediate:**
- The reaction starts with the formation of a zinc carbenoid from diiodomethane (\( \text{CH}_2\text{I}_2 \)) in the presence of the zinc-copper couple.
2. **Cyclopropanation:**
- This intermediate then reacts with the ethylene group on cyclopentene to form a three-membered cyclopropane ring.
3. **Product Structure:**
- The result is a bicyclic structure where a cyclopropane ring is fused to a cyclopentane ring.
The major product of this reaction can be drawn as follows (not the exact structure, but for explanation purposes):
