Question

The correct order of increasing hydration energy of the following conjugate bases of oxoacids of bromine is
​

Answer 1

Answer:

B

Explanation:

Hydrogen energy is the amount of energy released when one mole of ions undergo hydrogen which is a special case of solution.

Among two ions with same charge, the one with a smaller radius will have more hydration energy.

Hydrogen energy decreases down the group

(A) The extent of hydration of ion increases with increase in ionic size.

The ionic size of Li

+

>Be

+

Hence, Be

+

has greater hydration energy.

The correct option:−

(C) Na

+

<Mg

+2

Hydration energy depends on charge of ion and ionic radius. Higher the charge, greater the hydration energy.

Hence, Option (C) is correct.
