Question

Which of the following has correct increasing basic strength?

• A. \( \text{MgO} < \text{BeO} < \text{CaO} < \text{BaO} \)
• B. \( \text{BeO} < \text{MgO} < \text{CaO} < \text{BaO} \)
• C. \( \text{BaO} < \text{CaO} < \text{MgO} < \text{BeO} \)
• D. \( \text{CaO} < \text{BaO} < \text{BeO} < \text{MgO} \)

Hint:

The basic strength of oxides increases as we go down Group 2 of the periodic table.

Answer 1

The Correct Option is A

Step 1: Basic strength.
The basic strength of oxides increases as we move down the group. Thus, the correct order of basic strength is \( \text{MgO} < \text{BeO} < \text{CaO} < \text{BaO} \).
Thus, the correct answer is (1).
