Question

The tendency of group 14 elements to show + 2 oxidation state increases in the order of.

• A. C < Si < Sn < Pb < Ge
• B. C < Si < Ge < Sn < Pb
• C. Ge < Sn < Pb < C < Si
• D. Pb < Sn < Ge < C < Si

Answer 1

Answer: (B)

C < Si < Ge < Sn < Pb

Answer 2

: The tendency to show +2 oxidation state increases down the group. It is due to inability of $\mathrm { ns } ^ { 2 }$ electrons of valence shell to participate in bonding.
