Which of the following is not correct?

  • A
    Lead does not show catenation
  • B
    Buckminster fullerene contains 20 six-membered rings and 12 five--membered rings
  • C
    Stability order of $\mathrm{GeX}_2, \mathrm{SnX}_2$ and $\mathrm{PbX}_2$ is $\mathrm{GeX}_2 < $ $\mathrm{SnX}_2 < \mathrm{PbX}_2$
  • Correct answer
    D
    The number of metalloids in group 14 elements is 2

Solution

Metalloids in group $14=\mathrm{Ge}$ Non - metals $=\mathrm{C}, \mathrm{Si}$ Metals $=\mathrm{Sn}, \mathrm{Pb}$ Thus, Statement in option (d) is incorrect.

Hence, the correct answer is option: 'D'.
