Analyzing +4 | -1
Assertion: P4O10\mathrm{P}_4 \mathrm{O}_{10} dehydrates HNO3\mathrm{HNO}_3.

Reason: In P4O10\mathrm{P}_4 \mathrm{O}_{10} oxidation state of P\mathrm{P} is +5
View answer and explanation
Correct option: B
If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
Option B (If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion) is correct because while both statements are true, the high affinity of P4O10P_4O_{10} for water is what drives the dehydration, not the oxidation state of P.
