| (I) Solubility in aqueous solution:\[Be{{(HC{{O}_{3}})}_{2}}>Mg{{(HC{{O}_{3}})}_{2}}>Ca{{(HC{{O}_{3}})}_{2}}>Ba{{(HC{{O}_{3}})}_{2}}\] |
| (II) Stability: \[L{{i}^{\oplus }}>{{B}^{\Theta }}>{{C}^{\Theta }}>B{{e}^{\Theta }}\] |
| (III) Oxidising power: \[Br{{O}_{4}}^{\Theta }>Cl{{O}_{4}}^{\Theta }>I{{O}_{4}}^{\Theta }\] |
| (IV) Extent of hydrolysis: \[NC{{l}_{3}}>PC{{l}_{3}}>AsC{{l}_{3}}\] |
A) I, II
B) I, III, IV
C) II, III, IV
D) All of the above
Correct Answer: C
Solution :
[c] Statement (I) is CORRECT: II, III and IV are INCORRECT CORRECT statement for II; \[L{{i}^{\Theta }}>{{C}^{\Theta }}>{{B}^{\Theta }}>B{{e}^{\Theta }}\] CORRECT statement for III; \[Br{{O}_{4}}^{\Theta }>I{{O}_{4}}^{\Theta }>Cl{{O}_{4}}^{\Theta }\] CORRECT statement IV; \[AsC{{l}_{3}}>PC{{l}_{3}}>NC{{l}_{3}}\]
