Question

Which of the following statement is incorrect about the elements/compounds of group $14 ?$

• A. Silicones are polymeric organosilicon compounds
• B. $SiF _{4}$ has tetrahedral shape
• C. $Pb ^{2+}$ is less stable than $Sn ^{2+}$
• D. $Mg _{2} C _{3}$ is an allylide type of ionic carbide

Answer 1

Answer: (C)

Stability of $+2$ oxidation state increases down the group. 14 due to inert pair effect thus, $Pb ^{2+}$ is more stable than $Sn ^{2+}$
