Question

van der waals radius is:

• A. Twice the bond length
• B. Half the bond length
• C. Half the distance between centres of nuclei of two non bonded atoms of adjacent molecules in solid state
• D. Equal to covalent radius

Answer 1

The correct option is C Half the distance between centres of nuclei of two non bonded atoms of adjacent molecules in solid state

For noble gases, the atomic radius is determined from half the distance between centres of nuclei of two non bonded atoms in solid state.
Hence, C is the correct answer.
