Question: In which of the following options the order of arrangement does not agree with the variation of property indicated against it?
Options:
A) $ A{l^{3+}}<M{g^{2+}}<N{a^{+}}<{F^{-}} $ (increasing ionic size)
B) B < C < N < O (increasing first ionisation enthalpy)
C) $ I<Br<Cl<F $ (increasing electron gain enthalpy)
D) $ Li<Na<K<Rb $ (increasing metallic radius)
Show Answer
Answer:
Correct Answer: B
Solution:
(b, c) B < C < N < O (given I.P. order) B < C < O < N (correct) I < Br < Cl < F (given $ \Delta H _{eg} $ order) I < Br < F < Cl (Correct)
