Question

Question 3.40 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

concept : In group , oxidizing power { means tendency to gain electron } decreases from top to bottom as the size increases .

But in period , oxidizing power increases when we move left to right because size decreases.

Here, F, Cl, O, N are given .
Oxygen is more electronegative than Cl , hence, O is stronger oxidizing agent than Cl. Also F is the best electronegative element.hence, it is the best oxidizing agent.

Hence, order of oxidizing agents is F > O > Cl > N
Hence, Option (b) is correct .
