Question

Choose the correct options regarding the nature of oxides formed by $Li$ and $Be$ :

• A. $L{i}_{2}O$ is acidic while $BeO$ is basic.
• B. $BeO$ is amphoteric.
• C. $L{i}_{2}O$ is basic.
• D. $L{i}_{2}O$ and $BeO$ both are amphoteric.

Answer 1

Answer: (B), (C)

$BeO$ is amphoteric.
$L{i}_{2}O$ is basic.

In a period from left to right acidic natutre increases basic nature decreases.
So $L{i}_{2}O$ is basic.$BeO$ is amphoteric.
So options A & B are correct.
