Concept explainers
(a)
Interpretation:
The stronger acid has to be determined.
Concept Introduction:
Base and its conjugate Acid: A Base is a species that can gain a proton. When a base gains a proton
Electron delocalization stabilizes base: If a base has delocalized electrons, then the negative charge that results when the base’s conjugate acid loses a proton will belong to one atom. If a base has delocalized electrons, then the negative charge that results when the base’s conjugate acid loses a proton will be shared by two or more atoms. A base with delocalized electron is more stable than a similar base with localized electrons.
Relative Acid strength: Replacing hydrogen with an electronegative substituent that pulls bonding electrons toward itself increases the strength of the acid.
The more electronegative the substituent that replaces hydrogen, the stronger the acid becomes.
