The element that does not show catenation is

Options

  1. ASn
  2. BSi
  3. CGe
  4. DPb

Correct answer

D. Pb

Step-by-step solution

Catenation is the tendency to link with one another through covalent bonds to form chain and rings, i.e., catenation. This is because bonds are very strong in the carbon family. On moving down the group, the size increases and the tendency to show catenation decreases because bond enthalpy decreases. The order of catenation is C > Si > Ge > Pb . Pb does not show catenation.
