Question

$BeO$ is insoluble but $BaO$ is soluble as

• A. lattice energy of $BeO$ is higher than $BaO$ due to small size of $Be^{2+}$ ion and its covalent nature
• B. hydration energy of $BeO$ is lower than $BaO$ due to small size $Be^{2+}$ ion
• C. $BeO$ is amphoteric in nature while $BaO$ is basic
• D. $BeO$ forms hydrated salts while $BaO$ forms anhydrous salts

Answer 1

Answer: (A)

The lattice energy of $BeO$ is higher than $BaO$ due to small size of $Be^{2+}$ ion. $BeO$ is covalent while $BaO$ is ionic in nature.
