14. The correct order of radii is
$(2000,1 M)$
(a) $N < Be < $ B
(b) $F^{-} < O^{2-} < N^{3-}$
(c) $Na < Li < K$
(d) $Fe^{3+} < Fe^{2+} < Fe^{4+}$
Show Answer
Answer:
Correct Answer: 14. (b)
Solution:
- Among isoelectronic species, greater the negative charge, greater the ionic size, hence $F ^ {-} < O ^ {2-} < N ^ {3-} $.
