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.

Text Solution

Verified by Experts

The correct Answer is:
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.
