Give reason for the following observation(a)- The tendency for catenat

1.	Give reason for the following observation(a)- The tendency for catenation decreases down the group in group 14 (b)- The decreasing stability of+3 oxidation state with increasing atomic no. in group 13. (c)- Molten aluminum bromide is a poor conductor of electricity.
Answer» (a) it is due to decrease in bond dissociation energy which is due to increase in atomic size C-C > Si-Si >Ge-Ge>Sn-Sn>Pb-Pb. (b)- It is due to inert pair effect. (c)- Molten AlBr₃ is poor conductor of electricity because it is covalent compound.

Answer»

(a) it is due to decrease in bond dissociation energy which is due to increase in atomic size

C-C > Si-Si >Ge-Ge>Sn-Sn>Pb-Pb.

(b)- It is due to inert pair effect.

(c)- Molten AlBr₃ is poor conductor of electricity because it is covalent compound.
