Question

Assertion (A): Bismuth compounds are stable in +V oxidation state than in +III oxidation state.
Reason (R): Inert pair effect is observed in Bismuth compounds.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true and (R) is false
• D. (A) is false but (R) is true

Answer 1

The correct option is D (A) is false but (R) is true

Inert pair effect is observed in Bismuth compounds
So +III state is more stable than +V oxidation state
