Which of the following statement about fluorine is not correct?a)Elect...
Industrial production of fluorine entails the electrolysis of hydrogen fluoride in the presence of potassium fluoride. Under these conditions, the potassium fluoride (KF) converts to potassium bifluoride (KHF2), which is the actual electrolyte. This potassium bifluoride aids electrolysis by greatly increasing the electrical conductivity of the solution. Fluorine gas forms at the anode, and hydrogen gas at the cathode.
HF + KF → KHF2
2 KHF2 → 2 KF + H2 + F2
HF + KF → KHF2
2 KHF2 → 2 KF + H2 + F2

Fluorine and its Properties
Fluorine is a highly reactive and corrosive element with the atomic number 9 and symbol F. It belongs to the halogen group of elements and is the most electronegative element on the periodic table. Here, we will discuss each statement and determine why option 'C' is the incorrect statement.
a) Electron affinity of chlorine is greater than that of fluorine
The electron affinity of an element refers to the energy change that occurs when an atom gains an electron to form a negative ion. Fluorine has the highest electron affinity among all the elements. This is due to its small atomic size and high effective nuclear charge, which result in a strong attraction for electrons. Chlorine has a lower electron affinity compared to fluorine. Therefore, statement 'a' is correct.
b) Bond energy of fluorine is less than that of chlorine
Bond energy refers to the amount of energy required to break a covalent bond between two atoms. Fluorine forms a single covalent bond with another fluorine atom, known as a fluorine molecule (F2), which has a high bond energy. Chlorine also forms a single covalent bond with another chlorine atom, but its bond energy is lower than that of fluorine. Thus, statement 'b' is correct.
c) Fluorine cannot be prepared by electrolysis of fused metal fluorides
This statement is incorrect. Fluorine can indeed be prepared by the electrolysis of fused metal fluorides. This method is known as the electrolysis of molten fluorides. For example, the electrolysis of potassium fluoride (KF) or hydrogen fluoride (HF) can be used to obtain fluorine gas. Therefore, option 'C' is the incorrect statement.
d) Fluorine does not form oxoacid
Fluorine is a highly reactive element and can form compounds with numerous elements, including hydrogen and oxygen. While it is true that fluorine does not form stable oxoacids, it can still form unstable or transient oxoacids, such as hypofluorous acid (HOF) and perfluoric acid (HOF6). Therefore, statement 'd' is correct.
In conclusion, option 'C' is the incorrect statement because fluorine can be prepared by the electrolysis of fused metal fluorides.
