We're being asked to identify the stronger base and draw its Lewis structure.
Ka represents the acid dissociation constant and it measures the strength of weak acids. In general:
• The higher the Ka the stronger the acid and the greater the concentration of H+
pKa is the negative base-10 logarithm of the base dissociation constant (Ka) of a solution.
• The lower the pKa, the stronger the acid
Kb represents the base dissociation constant and it measures the strength of weak bases. In general:
Between these two compounds, NH2- or CH3COO-, draw the Lewis structure of the stronger base
Explicitly draw all H. Include all valence lone pairs in your answer.
