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).

![**Title: Ranking Protons by pKa in a Molecular Structure**
**Objective:**
Determine the order of the labeled protons in terms of increasing pKa values for the given molecule.
**Structure:**
The molecule features the following elements:
- An ether group to the left, connected to a cyclopentane ring.
- The cyclopentane ring is bonded to an oxygen atom with a double bond.
- Attached to the ring are two different groups:
- **Ha:** Located on the ether oxygen.
- **Hb:** Attached to the cyclopentane ring near the oxygen.
- A side chain extending from the ring contains:
- Fluorine atom bonded to a methine group.
- Connected to this group is:
- **Hc:** Near the fluorine atom.
- An additional ester functional group characterized by:
- A carbonyl oxygen and methoxy group.
- **Hd:** Hydrogen on the methoxy group.
**Task:**
Rank the protons (Ha, Hb, Hc, Hd) according to increasing acid dissociation constant (pKa). Lower pKa values indicate stronger acidity.
**Instructions:**
1. Analyze the electron-withdrawing and donating effects of surrounding atoms or bonds.
2. Consider the influence of functional groups on each hydrogen's acidity.
3. Complete the ranking by evaluating which protons are more acidic (lower pKa).
