Answer 1

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
