BOARD

Account for the following :

(i) Bi(V) is a stronger oxidizing agent than Sb(V).

(ii) N - N single bond is weaker than P - P single bond.

(iii) Noble gases have very low boiling points.

(i) Bi(V) is a stronger oxidizing agent than Sb(V) due to inert pair effect as the stability of lower oxidation state (+3) increases down the group.

(ii) Due to smaller size of Nitrogen, their lone pairs repel the bond pair of N -N bond while P - P due to bigger size does not show more repulsion.

(iii) Due to presence of weak Van der waal forces of attraction, noble gases have very low boiling point.
