Give reason why boron and aluminum tend of form covalent compounds.

Description : Give reason why boron and aluminum tend of form covalent compounds.

Last Answer : Ans. Sum of the three ionization enthalpies of both the elements are very high. Thus they have no tendency to lose electrons to form ionic compound. Instead they form covalent compounds.

Give reason for the following observation (L-III) (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.

Description : Give reason for the following observation (L-III) (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.

Last Answer : Ans. -(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.
