Phosphorus and Its Compounds
CHXI11:THE P-BLOCK ELEMENTS

316829 Assertion :
White phosphorus is more reactive than red phosphorus.
Reason :
Red phosphorus consists of \(\mathrm{P}_{4}\) tetrahedral units linked to one-another to form linear chains, which reduces strain.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
