The correct stability order of M+4 cations is
Correct answer: D. Ge+4 > Sn+4 > Pb+4
- A. Get4 < Pb+4 < Sn+4
- B. Ge+4 < Snt4 < Pb+4
- C. Get4 > Pb+4 > Sn+4
- D. Ge+4 > Sn+4 > Pb+4
Explanation
The stability order of M+4 cations generally depends on factors like the size of the cation, its effective nuclear charge, and the electronic configuration. Typically, for transition metals, the stability decreases with increasing charge density and oxidation state.

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.
