Solution Steps

Step 1: Identify the given compounds

The problem provides two compounds to compare their basicity. The first compound is an acetate ion (CH3COO-) and the second compound is an ethoxide ion (CH3CH2O-).

Step 2: Understand the concept of basicity

Basicity refers to the ability of a compound to accept protons (H+). A stronger base is more willing to accept a proton. The strength of a base is influenced by the stability of the conjugate acid formed after accepting a proton.

Step 3: Compare the stability of the conjugate acids
  • The conjugate acid of the acetate ion (CH3COO-) is acetic acid (CH3COOH).
  • The conjugate acid of the ethoxide ion (CH3CH2O-) is ethanol (CH3CH2OH).

Acetic acid is a stronger acid than ethanol, meaning that the acetate ion is more stable than the ethoxide ion. Therefore, the ethoxide ion is a stronger base because it is less stable and more willing to accept a proton.

Final Answer

The strongest base among the given compounds is the ethoxide ion (CH3CH2O-).
