Statement-1: Acetate ion is more basic than the methoxide ion.
Statement-2: The acetate ion is resonance stabilized.
Explanation:
Basicity of Acetate ion and Methoxide ion:
Basicity refers to the ability of a species to donate an electron pair. In general, the basicity of an anion increases with the stability of the conjugate acid formed when it accepts a proton.
The acetate ion (CH3COO-) and the methoxide ion (CH3O-) are both anions derived from weak acids, acetic acid (CH3COOH) and methanol (CH3OH), respectively. When these anions accept a proton, they form their respective conjugate acids.
The conjugate acid of the acetate ion is acetic acid (CH3COOH), which is a weaker acid compared to the conjugate acid of the methoxide ion, methanol (CH3OH). This implies that the acetate ion is more stable than the methoxide ion, making it less likely to accept a proton. Therefore, the methoxide ion is more basic than the acetate ion.
Resonance Stabilization of Acetate ion:
Resonance stabilization refers to the delocalization of electrons in a molecule or ion, resulting in increased stability. The acetate ion (CH3COO-) exhibits resonance stabilization due to the presence of a resonance structure.
In the acetate ion, the negative charge can be delocalized over both oxygen atoms through the pi bond. This delocalization of electrons increases the stability of the acetate ion. On the other hand, the methoxide ion does not possess any resonance structure.
Conclusion:
Therefore, Statement-1 is False. The methoxide ion is more basic than the acetate ion. Statement-2 is True. The acetate ion is resonance stabilized, which contributes to its stability.
Statement-2: The acetate ion is resonance stabilized.
