CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313153 Assertion :
Covalent radius of an element is always lesser than its van der Waal’s radius.
Reason :
Covalent radius is one half the distance between the nuclei of two covalently bonded atoms of the same element in a molecule whereas van der Waal’s radius is one half the distance between the nuclei of two non-bonded isolated atoms.

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If Assertion is false but Reason is true.
