Passage / Comprehension

Consider two closest $Cl_{2}$ molecules to find covalent and Vander Waals radii of Cl atom in chlorine molecule. The inner circles in figure correspond to the size of the chlorine atom.

Select CORRECT data which represent covalent radius of chlorine :

Options:

Answer:

Solution:

From the provided diagram, the internuclear distance (bond length) between two bonded chlorine atoms in a Cl₂ molecule is $198 p m$ .

The covalent radius is calculated as:

$C o v a l e n t r a d i u s = \frac{I n t er n u c l e a r d i s t an ce}{2} = \frac{198}{2} p m = 99 p m$

Therefore, the correct option representing the covalent radius of chlorine is (D).
