1.	The CORRECT order of radii is …………… (A) N < Be < B (B) F- < O2- <N3-(C) Na < Li < K(D) Fe3+< Fe2+ < Fe4+
Answer» Correct option is: (B) F^- < O^2-<N^3- Isoelectronic species with more negative changes have large ionic radii than less negative. Therefore, the correct order of radii is \(N^{3^\circ} > O^{2^\circ} > F^-\) (B) F^- < O^2- <N^3-

The CORRECT order of radii is …………… (A) N < Be < B (B) F- < O2- <N3-(C) Na < Li < K(D) Fe3+< Fe2+ < Fe4+

Answer»

Correct option is: (B) F^- < O^2-<N^3-

Isoelectronic species with more negative changes have large ionic radii than less negative. Therefore, the correct order of radii is \(N^{3^\circ} > O^{2^\circ} > F^-\)

(B) F^- < O^2- <N^3-
