Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

For chlorine, the van der Waals radius is \( 180\text{ pm} \) and the covalent radius is \( 99\text{ pm} \). Calculate the difference between the non-bonded internuclear distance between two chlorine atoms of adjacent molecules in solid chlorine and the bonded internuclear distance in a \( \text{Cl}_2 \) molecule.

1. A
   \( 162\text{ pm} \)
2. B
   \( 81\text{ pm} \)
3. C
   \( 261\text{ pm} \)
4. D
   \( 180\text{ pm} \)
