Question

Why F2O is not considered to be the oxide of fluorine???

Answer 1

Answer:

Fluorine is the most electronegative element. Its electronegativity is higher than oxygen. In naming a compound less electronegative elements is first and then more electronegative is can be used. Therefore or thus F2O or OF2 is known as oxygen difluoride and not fluorine oxide.

Thus F20 is not considered to be the oxide of fluorine.

Answer 2

F2O is not considered to be the oxide of fluorine because-

• In F2O, oxygen is in a -2 oxidation state while fluorine is in a +1 oxidation state. but it is not acceptable due to some rules of the oxidation state.
• Fluorine is a highly or most electronegative element of the periodic table. hence, its oxidation state cannot be positive.
• Fluorine is the most electronegative element of the periodic table and its oxidation state is always taken equal to -1.
• Besides this OF2 is possible because fluorine is in a -1 oxidation state whereas oxygen is in +2.
