Rank the following compounds in order of increasing acidity, and explain your ranking. -СООН -СООН Br E A A O₂N B COOH (least acidic) < C (most acidic) COOH The strongest acid has a strong electron-withdrawing group base. The weakest acid has a strong electron-donating group H₂C that will D B destabilize that will stabilize the E COOH Dositive D the negative charge in its conjugate charge in its
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.
For a carboxylic acid,
Electron withdrawing group enhances the acidity of the carboxylic acid
Electron donating group decreases the acidity of the carboxylic acid.
Among the given, -NO2 is the strongest Electron withdrawing group. So, B is the most acidic one.
-OCH3 is the strongest Electron donating group. So, C is the least acidic.
The order is
C (least acidic) < D < A < E < B (most acidic)
