**Question:**Which of the following protons has the lowest pKa?**Diagram and Explanation:**The image presents a question related to organic chemistry, specifically focusing on the acidity of protons in different molecular structures. It provides five different molecules labeled with specific protons Ha, Hb, Hc, Hd, and He. 1. **Ha:** Proton attached to a nitrogen in a pyrrole ring.2. **Hb:** Proton on a carbon adjacent to a double bond, part of an allylic system.3. **Hc:** Proton on a cyclohexane structure.4. **Hd:** Proton attached to a sulfur in a thiol group.5. **He:** Proton attached to an oxygen in an ether group.**Options:**1. Ha2. Hb3. Hc4. Hd5. He The task is to determine which of these protons is the most acidic, indicated by the lowest pKa value.

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
