1.	Which of the following orders are correct for property indicated in brackets ? .A. `NH_(3)gtNF_(3)gtBF_(3)` (dipole moment)B. `CI gt S gt O gt N` (electron affinity)C. `Si gt Mg gt A1 gt Na` (first ionisation enthalpy)D. `HCIO_(4) gt HBrO_(4) gt HIO_(4)(pK_(a) "values")`
Answer» Correct Answer - A::B::C All are correct and all conceptual statements (d) is wrong Correct order for `pK_(a)` value is `HIO_(4) gt HBrO_(4) gt HCIO_(4)` Acidic strenght `HCIO_(4) gt HBrO_(4) gt HIO_(4)` weaker the acid higher is its `pK_(a)` value .
