[Hint : Because it have polymeric structure consisting chains of P4 tetrahedra, hence denser than white P while red P is not having angular strain as in white P, hence...
[Hint : (i) 4
(ii) Because due to presence of vacant d-orbitals in the octet of 'p', it can
expand its octet to form PCl5, while N cannot expand its octet.]
Nitrogen owing to its small size has a tendency to form pπ−pπ multiple bonds with itself. Nitrogen thus forms a very stable diatomic molecule, N2. On moving down a group,...
Catenation is much more common in phosphorous compounds than in nitrogencompounds. This is because of the relative weakness of the N−N single bond as compared to the P−P single bond....
(b) White phosphorus exists as P4 tetrahedral molecule having P-P-P bond angle 60º. Hence the molecule is under strain and more reactive. On the other hand red phosphorus exists as...
