Answer:
(i)
Phosphorus is more
stable than nitrogen because
of angle strain in molecule
where the angles are only 60° rather than 109°28' (due to
tetrahedral shape).
Nitrogen is inert at room temperature because of high bond
enthalpy of N = N bond.
(ii) In vapour state sulphur exists as 83 molecule which
has two unpaired electrons in the antibonding orbitals like Og and hence
exhibit paramagnetism. 1
(iii) Nitric acid decomposes which is
brown colour in which makes turns
yellow. 1
