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.

Text Solution

Verified by Experts

(i) Because the presence of f - orbital electrons, Bi is more stable in `+3` oxidation state than that of Sb.
(ii) Because of interelectronic repulsion showing to small bond length of `N-N`/smaller size of nitrogen atom.
(iii) Because of weak dispersion forces.
