1.	Catenation i.e., linking of similar atoms depends on size and electronic configuration of atoms. The tendency of catenation in group-14 elements follows the order :
Answer» `C GT Si gt Ge gt Sn` `C gt gt Si gt Ge approx Sn` `Si gt C gt Sn gt Ge` `Ge gt Sn gt Si gt C` Solution :On MOVING down the group the SIZE of the atom increases and the bond ENERGY decreases and property of catenation decreases. In group-14 carbon shows maximum catenation. `C gt gt Si gt Ge approx Sn gt Pb`
