Assertion (A): Salts of `CIO_(3)^(Theta)` and `CIO_(4)^(Theta)` are we – InterviewSolution

InterviewSolution

1.	Assertion (A): Salts of `CIO_(3)^(Theta)` and `CIO_(4)^(Theta)` are well known but those of `FO_(3)^(Theta)` are unknown. Reason (R ): F is more electronegative than O, while CI is less electronegative than O.
Answer» Correct Answer - B Correct Reason: F cannot show positive oxidation state of `+5` and `+7`, due to absence of vacant d-orbital in its valence shell, hence `FO_(3)^(Theta)` and `FO_(4)^(Theta)` are unknown.
