Question

(D) The size of alkali metal ions increases down the group as follows: $Li ^{+} < Na ^{+} < K ^{+} < Rb ^{+} < Cs ^{+}$.Hydration enthalpy is inversel

Vedclass · Accepted Answer

$Li ^{+} > Na ^{+} > K ^{+} > Rb ^{+} > Cs ^{+}$

Vedclass · Answer

(D) The size of alkali metal ions increases down the group as follows: $Li ^{+} Hydration enthalpy is inversely proportional to the ionic size $(Hydration \ Enthalpy \ \propto \ \frac{1}{	ext{ionic size}})$.Therefore,the smaller the ion,the higher its hydration enthalpy.Thus,the correct order of hydration enthalpies is $Li ^{+} > Na ^{+} > K ^{+} > Rb ^{+} > Cs ^{+}$.

The correct order of hydration enthalpies of alkali metal ions is
