Which of the following statements is incorrect about fluorine
Correct answer: B. The correct answer is (b) fluorine follows octet rule and as well as extended octet rule.
- A. Fluorine is restricted to -1 oxidation state
- B. The correct answer is (b) fluorine follows octet rule and as well as extended octet rule.
- C. Fluorine has the lowest dissociation energy among the halogens
- D. both b& c
Explanation
Incorrect statement:Fluorine cannot break the octet rule: It lacks d-orbitals in its valence shell, so it cannot accommodate more than 8 electrons in its outermost shell. This restriction prevents it from forming compounds that require an extended octet.Correct statements:(a) Fluorine is restricted to -1 oxidation state: Due to its high electronegativity, fluorine always gains one electron to achieve a stable noble gas configuration, resulting in a -1 oxidation state in its compounds.(c) Fluorine has the lowest dissociation energy among the halogens: It has the shortest bond length and the strongest interatomic repulsion among the halogens, making it relatively easier to break the F-F bond.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
