Which of the following is only acidic in nature?
Correct answer: C. B(OH)3
- A. Be(OH)2
- B. Mg(OH)2
- C. B(OH)3
- D. Al(OH)3
Explanation
Boric acid, B(OH)₃, is a weak Lewis acid, accepting an OH⁻ ion from water rather than donating a proton. Beryllium and aluminium hydroxides are amphoteric, while magnesium hydroxide is basic.

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.
