Which of the following ions has largest heat of hydration?
Correct answer: D. Be2+
- A. Ba2+
- B. K+
- C. Li+
- D. Be2+
Explanation
Be2+ has the largest heat of hydration due to its small size and high charge, leading to high polarising power and attraction of multiple water molecules. The other options have relatively low heat of hydration due to their larger size and/or lower charge.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.

Which one of the following characteristics of lithium does not resemble with other alkali metals?
A solid compound 'X' on heating gives CO2 gas and a residue. The residue mixed with water forms 'Y'. On passing an excess of CO2 through 'Y' in water, a clear solution, 'Z' is obtained. On boiling 'Z', compound 'X' is reformed. The compound 'X' is:
Be and Al exhibit many properties which are similar. But the two elements differ in:
One mole of magnesium nitride on the reaction with an excess of water gives:
The substance not likely to contain CaCO3 is :
A metal M readily forms it sulphates MSO4 which is water soluble. It forms its oxides MO which becomes inert on heating. It forms an insoluble hydroxide M(OH)2 which is soluble in NaOH solution. Then M is:
