Which of the following order is incorrect:
Correct answer: C. F<O<N ⇒ order of oxidizing property
- A. I+<I <I- ⇒ order of size.
- B. Se <S <Cl ⇒ order of ionisation energy.
- C. F<O<N ⇒ order of oxidizing property
- D. Na <Mg <Al ⇒ order of electronegativity.
Explanation
N<O<F is correct order of oxidizing property, as oxidizing property increases in a period. Therefore option C is correct.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
