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

Consider the following orders:
(i) HF > HCl > HBr > HI : Acidic strength
(ii) `CH_2 lt "CCl"_4 gt CF_4 ` : Electronegativity of central 'C' - atom (iii) `Mg^(2+) lt K^(+) lt S^(2-) lt Se^(2-) ` : Ionic radius
(iv) Ni > Pd > Pt : Ionic radius
(v) `As^(5+) gt Sb^(5+) gt BI^(5+)` : Stable oxidation state
(vi) `Li^(+) lt Mg^(2+) lt Al^(3+) ` : Hydration energy
(vii) Cl > Br > F > I : Electron affinity
How many of these are correct orders?

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
