Interpretation:
The most acidic hydrogens present in the given compound should be identified.
Concept introduction:
Strong Acids: Acids that dissociates into ions completely which results in easy donation of protons are considered as strong acids. Strong acid forms weaker conjugated base.
Weak Acids: Acids that do not easily dissociate into ions completely which has difficulty in proton donation are considered as weak acids. Weak acid forms stronger conjugated base
Electrostatic potential map: It is 3D representation of molecules which shows the distribution of charges present in the molecule. Generally red, orange, yellow, green and blue defines the charge potentials present in the molecule.
The blue color indicates the most positive potential end and the red color defines the most negative potential end.
