Answer:
Name and formula Name Formula
(1) Nitrogen: Ammonia Nitric Acid NH3
HNO3
(2) Phosphorous: Phosphine PH3
(ii) Basic property: Ammonium is a mono basic anhydride that dissolves in water in in form of NH4OH (ammonium) hydroxide.
Ammonium hydroxide is a base. Hence, it has a more basic nature. Nitric acid is also a strong mono-basic acid which ionized in water and form of H3O+ and NNO3− ions.
Hence, it has also more basic nature. Phosphene combine with halogen acids in gaseous state and forms phosphonium. There phosphonium halides decompoe as soon as possible and reform phospone.
PH3+HX→Phosphonium halidePH4X [X = Cl, Br or I]
PH4XH2OPH3−H+X
Hence it has more acidic property due to formation of H+ and it has also more basic nature.
Therefore, it is clear that hydrides of Nitrogen and Nitrogen family has more basic nature.
(ii) Reducing property: Ammonia gas is a strong reducing agent. It reduces hot metallic oxides into metals.
Nitric acid is a strong oxidant i.e. reducing agent, as it easily decomposes to produce nascent oxyen.
2HNO3→H2O+2NO2+Nitrogen di-oxide[O]
On passing phosphene gas into the solutions of copper silver and mercury salts metal phosphides are precipitated.
3CuSO4+2PH3→Cu3P2+3H2SO4
3HgNO3+PH3→Ag3P+3HNO3
Hence, it has strong reducing property.
Therefore, from the above reasons and explanation it is clear that hydrogen of nitrogen family have strong reducing property.
(iv) Bond angle Ammonia: (ref. image)
Bond angle is 107.3
