P-Block Elements -II Important Questions JEE

To strengthen your JEE Chemistry preparation, we have listed important questions from The p-Block Elements – II below.  

These questions cover all major topics, including trends, reactions, and compounds from Groups 15 to 18. Go through P-Block Elements -II Important Questions JEE carefully to test your understanding and boost your exam readiness.

1. What is Ostwald’s process for the preparation of nitric acid?

Answer:
In the Ostwald process, ammonia is oxidised to nitric oxide using a Pt/Rh catalyst at 500 K and 9 bar pressure.
Steps:
(i) 4NH₃ + 5O₂ → 4NO + 6H₂O
(ii) 2NO + O₂ → 2NO₂
(iii) 3NO₂ + H₂O → 2HNO₃ + NO

2. Why does concentrated nitric acid appear yellow? Explain.

Answer:
Concentrated HNO₃ appears yellow due to decomposition by sunlight, forming nitrogen dioxide (NO₂), which is a brown gas imparting yellow colour to the acid.

3. Give one reaction showing nitric acid as an oxidising agent.

Answer:
Cu + 4HNO₃ (conc.) → Cu(NO₃)₂ + 2NO₂ + 2H₂O

4. What is the action of nitric acid on non-metals? Give the equation.

Answer:
Hot and concentrated nitric acid converts non-metals into their highest oxyacids, releasing NO₂ gas.
Example: S → H₂SO₄, P → H₃PO₄, I₂ → HIO₃.

5. Write one reaction showing the action of dilute HNO₃ on zinc.

Answer:
4Zn + 10HNO₃ (dilute) → 4Zn(NO₃)₂ + 5H₂O + N₂O

6. What are the oxidation states shown by nitrogen and phosphorus?

Answer:
Nitrogen shows oxidation states from –3 to +5, while phosphorus shows –3, +1, +3, and +5. Intermediate states tend to disproportionate into +5 and –3.

7. Write the reaction for the preparation of phosphine (PH₃).

Answer:
Ca₃P₂ + 6H₂O → 3Ca(OH)₂ + 2PH₃

8. Mention one physical property of phosphine.

Answer:
Phosphine is a colourless gas with a smell of garlic or rotten fish and is slightly soluble in water.

9. What happens when phosphine is heated?

Answer:
4PH₃ → P₄ + 6H₂ (at 713 K)

10. How is sulphuric acid manufactured by the contact process?

Answer:
(i) 2SO₂ + O₂ ⇌ 2SO₃ (in presence of V₂O₅ at 450°C)
(ii) SO₃ + H₂SO₄ → H₂S₂O₇
(iii) H₂S₂O₇ + H₂O → 2H₂SO₄

11. Give one use of sulphuric acid.

Answer:
It is used in the manufacture of paints, pigments, and fertilizers, and in lead storage batteries.

12. Arrange the halogens in order of decreasing reactivity.

Answer:
F₂ > Cl₂ > Br₂ > I₂

13. Write one displacement reaction involving halogens.

Answer:
2KBr + Cl₂ → 2KCl + Br₂

14. What is meant by interhalogen compounds? Give examples.

Answer:
Interhalogen compounds are formed when two different halogens combine, one being more electropositive.
Examples: ClF, BrF₃, IF₅, IF₇.

15. Which is the first noble gas compound discovered?

Answer:
O₂[PtF₆] is the first noble gas compound discovered, formed by the reaction of oxygen with platinum hexafluoride.
