NEET2018Chemistryp Block Elements (Group 13 & 14)Actual
Assertion : Pb ₃ O ₄ reacts with HNO ₃ and forms PbO ₂ . Reason : Lead is stable in +4 oxidation state.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
C. If assertion is true but reason is false.
Step-by-step solution
aligned & Pb ₃ O ₄+ HNO ₃ PbO ₂( solid )+ & Pb ( NO ₃ )₂+ H ₂ O aligned but Pb ²⁺ is more stable due to inert pair effect.
