1.	Which of the following ions has the maximum hyration enthalpy?A. `Be^(2+)`B. `Mg^(2+)`C. `Ca^(2+)`D. `Sr^(2+)`
Answer» Correct Answer - A Like alkali metal ions,the hydration enthalpies of alkaline earth metal ions decrease withh increase in ionic size down te group: `Be^(2+) gt Mg^(2+) gt Ca^(2+) gt Sr^(2+) gt Ba^(2+)`
