The correct order of covalent radii of Si , Ge , Sn is:

Options

  1. AGe < Si < Sn
  2. BSn < Si < Ge
  3. CSi < Ge < Sn
  4. DSn < Ge < Si

Correct answer

C. Si < Ge < Sn

Step-by-step solution

As we move down the group, the addition of shells causes an increase in the covalent radii of the group 14 elements. Thus, Si < Ge < Sn .
