Question

Assertion :$Cs{l}_3$ is an ionic compound. Reason: It contains $C{s}^{3+}$ and $l^{-}$ ions

• A. Both Assertion and Reason are true and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation for Assertion
• C. Assertion is true statement but Reason is false
• D. Both Assertion and Reason are false statement.

Answer 1

The correct option is C Assertion is true statement but Reason is false

• When we consider Cs it belongs to the first group so the oxidation must be +1 Then ultimately the other will be $I_3^{-}$.
  
• It forms ionic compound since from the top to bottom ionic nature increases so both combinely forms ionic compound.
