Assertion: Chemistry of actinoids is more complicated than lanthanoids. Reason: Actinoid elements are radioactive.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

Chemistry of actinoids is more complicated due to the possibility of large number of oxidation states.
