Question

Considering the elements F, Cl, O and N, the correct order of their chemical reactivity in terms of oxidizing property is:(a) F > Cl > O > N(b) F > O > Cl > N(c) Cl > F > O > N (d) O > F > N > Cl

Answer 1

the correct answer is B option

Answer 2

All these elements are p block elements

The oxidizing character of elements increases from left to right across a period because of presence of vacant d orbitals in their valency shells

Thus, we get the decreasing order of oxidizing property as F > O > N.

Again, the oxidizing character of elements decreases down a group.

Thus, we get F > Cl.

However, the oxidizing character of O is more than that of Cl i.e., O > Cl.

Hence, the correct order of chemical reactivity of F, Cl, O, and N in terms of their oxidizing property is F > O > Cl > N.
