Question

BeO is insoluble but BaO is soluble. Give reson.

• A. Lattice energy of BeO is higher than BaO due to small size of $Be^{+}$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)

Lattice energy of BeO is higher than BaO due to small size of $Be^{+}$ion and its covalent nature.

Answer 2

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