Given two statements below :
Statement I : In molecule the covalent radius is double of the atomic radius of chlorine.
Statement II : Radius of anionic species is always greater than their parent atomic radius.
Choose the most appropriate answer from options given below
Options
- ABoth Statement I and Statement II are correct.
- BBoth Statement I and Statement II are incorrect.
- CStatement I is correct but Statement II is incorrect.
- DStatement I is incorrect but Statement II is correct.
Correct answer
D. Statement I is incorrect but Statement II is correct.
Step-by-step solution
In molecule, the covalent radius is half of the internuclear distance, so statement is false. The covalent radius is little smaller than the actual radius of the atom of chlorine due to overlapping during formation of covalent bond.
For the same element, anion has lower effective nuclear charge than atom so, anion is larger than the parent atom. That means statement is correct.
