- (d) Such questions can be solved by considering the relative basic character of their conjugated bases which for
More the possibility for the dispersal of the negative charge, weaker will be the base. Thus the relative basic character of the four bases is
Equivalent Non-equivalent Oxygen can accommodate
resonating structures
Due to resonance
Thus, the acidic character of the four corresponding acids wil be
