Interpretation:
Acidic nature of the given set of compounds should be identify based on pKa concept
Concept introduction:
Resonance:
To delocalized electrons within the certain molecules or by polyatomic ions, where the bonding cannot be expressed by one Lewis structure. This phenomenon is also called “mesmerism”.
A molecule or ion with delocalized electrons are represented by several contributing structure’s it is also called “resonance or canonical structure’s”.
PKa:
The pKa is a measure of acid strength. It depends on the chemical properties of the acid. If the pKa value is smaller, the substance is more acidic (which means it’s lost their proton easily).
If pKa in negative base-10, logarithm of the dissociation constant of acid (Ka) of a solution.
