Question

The covalent and vander Waals radii of chlorine respectively are

• A. and
• B. and
• C. and
• D. and

Answer 1

Answer: (B)

Explanation:

• Van der walls radii >> covalent radius .
• Van der walls radius is measured in non-bonding condition and thus is very large.
• Covalent radius is measured from covalent bond length.​
• The covalent bond is a strong bond and bond length is shorter in this case.
• Therefore covalent radius is much shorter than that of van der walls radius.

Hence, option (B) is correct.
