Consider the following orders: (i) HF ...

Consider the following orders:
(i) `HF gt HCl gt HBr gt HI`: Lewis basic character.
(ii) `CH_(4) lt C Cl_(4) lt CF_(4)`: Electornegativityy of central 'C'-atom.
(iii) `Mg^(2+) lt K^(+) lt S^(2-) lt Se^(2-)`: ionic radius
then calculate vlaue of `|x-y|^(2)`, where x and y are correct and incorrect order respectively.

Text Solution

Verified by Experts

The correct Answer is:
4
(i) `CH_4 lt "CCl"_4 gt CF_4` : Electronegativity of central ‘C’-atom
(ii) `Mg^(2+) lt K^(+) lt S^(2-) lt Se^(2-)` : : Ionic radius
(iii) ` As^(5+) gt Sb^(5+) gt Bi^(5+)` Stable oxidation state
(iv) ` Li^(+) lt Mg^(2+) lt Al^(3+)` : Hydration energy
