The covalent radius in a chlorine molecule and van der Waal’s radius between chlorine molecules respectively can be ________ & _________

A. 99pm, 198pm

B. 198pm, 99pm

C. 198pm, 198pm

D. 99pm, 99m

The question was asked in homework.

This key question is from Bond Parameters in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Correct choice is A. 99pm, 198pm

Explanation: The half of the distance between two covalently bonded similar atoms in the same molecule is called covalent radius, whereas the half of the distance between two similar atoms of different molecules in a solid is known as van der Waal’s radius. Therefore covalent radius is smaller than the van der Waal’s radius.
