(a) $M g O$

(b) $B e O$

(d) $B a O$

[2018]

Show Answer

Solution:

(b) In metals, moving down the group, metallic character increases, so basic nature increases hence most acidic will be $B e O$ .

$\to_{increasing basic character}^{B e O < M g O < C a O < B a O}$ (a) $B e H_{2} < C a H_{2} < B a H_{2}$ Smaller the size of cation, more will be its polarising power. Hence, $B e H_{2}$ will be least ionic.
