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 ( H + ) , it forms its conjugate acid. In order to gain a proton, a base must possess lone pair that it can use to form a new bond with the proton. Neutral base forms a positively charged conjugate acid, whereas a positively charged base forms a neutral conjugate acid. 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. Example:

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
