NEET2019ChemistryClassification of Elements and Periodicity in PropertiesActual

Assertion: The electron gain enthalpy of N is +ve while that of P is -ve. Reason : This is due to the smaller atomic size of N in which there is a considerable electronelectron repulsion and hence the additional electron is not accepted easily.

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
