Match the entries of column I with appropriate entries of coloumn II. Each entry in column I may have one or more than one correct option from column II. If the correct matches are A-p, s , B-r, C-p, q , D-s, then the correctly bubbled 4 `xx` 4 matrix should be as follows :
`{:(,"Column I",,"Column II"),((A),SO_(2),(p),"Basic"),((B),H_(2)SO_(4),(q),"Acidic"),((C),HNO_(3),(r),"Reducing"),((D),NH_(3),(s),"Oxidising"):}`

Answer

To solve the problem of matching the entries from Column I with the appropriate entries from Column II, we will analyze each compound and determine its properties.

### Step-by-Step Solution:

1. **Identify the properties of SO₂ (A)**:
- SO₂ (sulfur dioxide) has sulfur in the +4 oxidation state.
- It can act as both an acid and an oxidizing agent.
- Therefore, SO₂ matches with:
- **p** (Basic)
- **q** (Acidic)
- **r** (Reducing)
- **s** (Oxidizing)

2. **Identify the properties of H₂SO₄ (B)**:
- H₂SO₄ (sulfuric acid) has sulfur in the +6 oxidation state.
- It is a strong acid and can act as an oxidizing agent.
- Therefore, H₂SO₄ matches with:
- **q** (Acidic)
- **s** (Oxidizing)

3. **Identify the properties of HNO₃ (C)**:
- HNO₃ (nitric acid) has nitrogen in the +5 oxidation state.
- It is primarily an acid and does not act as a reducing agent.
- Therefore, HNO₃ matches with:
- **q** (Acidic)

4. **Identify the properties of NH₃ (D)**:
- NH₃ (ammonia) has nitrogen in the -3 oxidation state.
- It can act as a reducing agent and can also behave as a weak acid.
- Therefore, NH₃ matches with:
- **p** (Basic)
- **r** (Reducing)

### Final Matches:
- A (SO₂) matches with **p, q, r, s**
- B (H₂SO₄) matches with **q, s**
- C (HNO₃) matches with **q**
- D (NH₃) matches with **p, r**

### Summary of Matches:
- A: p, q, r, s
- B: q, s
- C: q
- D: p, r

### Correctly bubbled matrix:
```
{:(,"Column I",,"Column II"),
((A),SO₂,(p),"Basic"),
((A),SO₂,(q),"Acidic"),
((A),SO₂,(r),"Reducing"),
((A),SO₂,(s),"Oxidising"),
((B),H₂SO₄,(q),"Acidic"),
((B),H₂SO₄,(s),"Oxidising"),
((C),HNO₃,(q),"Acidic"),
((D),NH₃,(p),"Basic"),
((D),NH₃,(r),"Reducing"):}
```
