MCQ
For which of the following ionic species radius would be maximum ?
- ✓$C ^{4-}$
- B$N ^{3-}$
- C$O ^{2-}$
- D$Mg ^{2+}$
✓
Answer
Correct option: A.
$C ^{4-}$
a
Cation has small size than parent atom and anion has greater size than parent atom. The anion which have more negative charge have maximum ionic species radius. Thus the correct answer is $C ^{4-}$.

Assertion : Reaction quotient is defined in the same way as equilbrium constant at any stage of the reaction.
Reason : If $Q_c$ (reaction quotient) $ < K_C$ (equilibrium constant) reaction moves in direction of reactants.
