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).
![### Major Product of the Given Reaction
**Question:**
What is the major product of the reaction below?
The given reaction involves:
- Benzene (C₆H₆)
- Acetyl chloride (CH₃COCl)
with the catalyst **AlCl₃** (Aluminum chloride).
The possible products are:
**Option A:**
- Structure that shows acetophenone (a benzene ring bonded to a carbonyl group [C=O] which is connected to a methyl group [CH₃]).
**Option B:**
- Structure that shows 3-acetyl acetophenone (a benzene ring bonded to two carbonyl groups separated by a single carbon).
**Option C:**
- Structure that shows 2-acetyl benzaldehyde (a benzene ring bonded to an aldehyde [CHO] orgroup and acetophenone [C=O]).
**Option D:**
- Structure that shows 4-acetyl benzaldehyde (a benzene ring bonded to an aldehyde [CHO] group and acetophenone [C=O]).
### Detailed Description of Structures:
- **Benzene molecule (C₆H₆):** A six-carbon ring structure with alternating double bonds (aromatic ring).
- **Acetyl chloride (CH₃COCl):** A molecule with a carbonyl group (C=O) directly bonded to a chloride atom (Cl), and also bonded to a methyl group (CH₃).
**Reaction Conditions:**
- The reaction is directed by AlCl₃ (Aluminum chloride), acting as a Lewis acid catalyst, facilitating the electrophilic aromatic substitution.
**Option Descriptions:**
- **Option A:** Shows a benzene ring substituted at one position with an acetophenone group (C₆H₅COCH₃).
- **Option B:** Shows a benzene ring substituted with a carbonyl group (C=O) bonded to CH₃ at one position, and another carbonyl group at the meta position related to the first one.
- **Option C:** Shows a benzene ring substituted with a carbonyl group bonded with a CH₃ (C=O) at one position, and an aldehyde group (CHO) at the para position related to the first one.
- **Option D:** Shows a benzene ring substituted at one position with a carbonyl group (C=O)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7eb32d09-79f1-492f-b21e-e525fbfadae0%2F244c2fd6-676b-4805-8843-ad681cea5fd7%2F1hv4l8e_processed.jpeg&w=3840&q=75)
