Given below are two statements :
Statement (I) : The radii of isoelectronic species increases in the order.
Mg²⁺ < Na⁺ < F⁻ < O²⁻
Statement (II) : The magnitude of electron gain enthalpy of halogen decreases in the order.
Cl > F > Br > I
In the light of the above statements, choose the most appropriate answer from the options given below :
Multiple Choice Options
- A Statement I is incorrect but Statement II is correct
- B Both Statement I and Statement II are correct
- C Statement I is correct but Statement II is incorrect
- D Both Statement I and Statement II are incorrect
Step-by-Step Verified Solution
(i) For isoelectronic species -ve charge increases, radii increases.
(ii) Magnitude of E.G.E : \mathrm{Cl}>\mathrm{F}>\mathrm{Br}>\mathrm{I}
