Question

Group 15 of the periodic table consists of the elements $N,P,As$, $\text{Sb}$ and $\text{Bi}$. On passing from $N$ to Bi, the oxides of the elements of general formula $M_2{O}_3$ becomes :

• A. strong reducing agents
• B. more ionic
• C. more basic
• D. more volatile

Answer 1

The correct option is C more basic

As we move down the group basicity of oxides increases because metallic character increases.
