CHM 102 P block elements Objective Question

Question

What is the general trend in basicity for the dioxides of Group 14 elements as one descends the group?
Options
A Basicity increases.
Correct Answer
B Basicity decreases.
C Basicity remains constant.
D Basicity first decreases then increases.
Correct Answer

Option A is the correct answer.

Detailed Explanation

Page 19 shows a diagram where 'Decreasing Basicity' is listed from CO₂ down to PbO₂. This implies that as you descend the group, the basicity increases (PbO₂ is more basic than CO₂).

Hint

Recall the general trend for metallic character and oxide basicity in groups.
