The tendency of catenation in Group 14 elements follows the order: (i) C > Si > Ge > Sn (ii) C >> Si > Ge ≈ Sn (iii) Si > C > Sn > Ge (iv) Ge > Sn > Si > C Solution: Option (ii) is the answer. 8. Silicon has a strong tendency to form polymers like silicones. The chain length of silicone, a polymer can be controlled by adding how increase ferritin levelWebSilicon dioxide is soluble in hot aqueous base; thus, strong bases destroy the passivation. Removal of the passivation layer allows the base to dissolve the silicon, forming hydrogen gas and silicate anions.
