Which of the following hydroxides of IIA group elements is insoluble in water?
Correct answer: A. Be(OH)2
- A. Be(OH)2
- B. Ca(OH)2
- C. Sr(OH)2
- D. Ba(OH)2
Explanation
The correct answer is Be(OH)2 because it is the most insoluble hydroxide among the IIA group elements. Calcium hydroxide, strontium hydroxide, and barium hydroxide are all more soluble in water compared to Be(OH)2, making them incorrect choices for this question.

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.

Consider the following statements which illustrate the anomalous properties of lithium and its diagonal relationship with magnesium:I. The melting point and boiling point of lithium are comparatively high like Mg.II. Lithium is much harder than the other alkali metals. Magnesium is also a hard metal.III. Lithium reacts with oxygen least readily to form normal oxide whereas other alkali metals form peroxides and super-oxides. Magnesium also forms normal oxide.IV. LiOH like Mg(OH)2 is a weak base. Hydroxides of other alkali metals are strong bases.Which of the above statements is/are correct?
