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).
Draw the structure of the starting material A for the reaction below when one equivalent of H2/Pt is present.
![**Title: Understanding Hydrogenation Reactions in Organic Chemistry**
**Introduction:**
In this exercise, we focus on the hydrogenation reaction, a process used to convert unsaturated organic compounds to saturated ones by the addition of hydrogen. This transformation is catalyzed by metals such as platinum (Pt).
**Reaction Description:**
The reaction under consideration involves the conversion of a compound labeled **A** to a cyclohexane derivative in the presence of hydrogen (H₂) and a platinum (Pt) catalyst. The product structure is a cyclohexane ring with two single bonds protruding from opposite sides.
**Objective:**
Your task is to draw the structure of the starting material **A**. Given that the reaction conditions include one equivalent of H₂/Pt, we infer that **A** is likely an unsaturated hydrocarbon that undergoes hydrogenation to form the saturated cyclohexane ring depicted.
**Understanding the Reaction Mechanism:**
- Hydrogenation with H₂ and Pt typically occurs by adding hydrogen across double or triple bonds.
- The final structure is a cyclohexane, which suggests **A** may initially possess a six-membered ring structure with multiple double bonds (e.g., benzene or cyclohexene).
**Conclusion:**
To complete this task, identify a likely structure for **A** that, upon hydrogenation, yields the saturated cyclohexane ring shown in the product. The exercise reinforces understanding of catalytic hydrogenation and its role in chemical synthesis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F33788b53-d84e-4c6e-bc46-c2e42ecf92bd%2F76f9cfd3-ed78-48ee-b9a6-9774f693eb2e%2Frv9d3o_processed.png&w=3840&q=75)
