For the element F, Cl, O and N correct order of their chemical reactivity in terms of oxidising property is:

Options

A. `F gt Cl gt O gt N`
B. `F gt O gt Cl gt N`
C. `Cl gt F gt O gt N`
D. `O gt F gt N gt Cl`.

Answer

B

Explanation

Oxidising power increases across a period from left to right. Thus, order of oxodising power decreases in the order FgtOgtN. on moving down a group, oxidisng power decreases, So, F is a stronger oxidising agent than Cl. Again, O being more electronegative than Cl, O is a stronger oxidising agent than Cl. therefore, overall decreasing order of oxidising power is FgtOgtClgtN.
