प्रश्न
Considering the elements F, Cl, O and N, the correct order of their chemical reactivity in terms of oxidizing property is ______.
विकल्प
F > Cl > O > N
F > O > Cl > N
Cl > F > O > N
O > F > N > Cl
उत्तर
Considering the elements F, Cl, O and N, the correct order of their chemical reactivity in terms of oxidizing property is F > O > Cl > N.
Explanation:
The oxidizing character of elements increases from left to right across a period. 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.
