  • a)
    I and II
  • b)
    I and III
  • c)
    III Only
  • d)
    II and III
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider the following experimental facts,I. When Cl2 gas is passed in...
Oxidising power of F2 > CI2 > Br2 > l2


Thus, (II) is true.

In experiment (III), orange colour of Br2 does not appear, as it also oxidises Kl to l2. Hence , only violet colour appears in CHCI3 layer. Thus, (III) is also true.

Consider the following experimental facts,I. When Cl2 gas is passed in...
Experimental Facts:
I. When Cl2 gas is passed into KI solution containing CHCl3, violet colour appears in CHCl3 layer.
II. When Cl2 gas is passed into KBr solution containing CHCl3, orange colour appears in CHCl3 layer.
III. When Cl2 gas is passed into a solution containing KBr, KI, and KCl, containing CHCl3, violet colour appears in CHCl3 layer.

Explanation:
- The experimental facts mentioned involve the reaction between Cl2 gas and different halide ions (I-, Br-, and Cl-) in the presence of CHCl3.

Fact I:
- When Cl2 gas is passed into KI solution containing CHCl3, violet colour appears in CHCl3 layer.
- This observation indicates the formation of an intermediate complex between Cl2 and I- ions.
- The formation of this complex leads to the extraction of I2 from the KI solution into the CHCl3 layer, resulting in the violet colour.

Fact II:
- When Cl2 gas is passed into KBr solution containing CHCl3, orange colour appears in CHCl3 layer.
- This observation suggests the formation of an intermediate complex between Cl2 and Br- ions.
- The formation of this complex leads to the extraction of Br2 from the KBr solution into the CHCl3 layer, resulting in the orange colour.

Fact III:
- When Cl2 gas is passed into a solution containing KBr, KI, and KCl, containing CHCl3, violet colour appears in the CHCl3 layer.
- This observation indicates the formation of an intermediate complex between Cl2 and I- ions.
- Similar to Fact I, the formation of this complex leads to the extraction of I2 from the KI solution into the CHCl3 layer, resulting in the violet colour.
- The presence of KBr and KCl in the solution does not affect the extraction process.

Conclusion:
- Based on the given experimental facts, the correct combination is II and III.
- Fact II demonstrates the extraction of Br2 into the CHCl3 layer, while Fact III demonstrates the extraction of I2 into the CHCl3 layer.
- Fact I, although mentioned separately, is essentially the same as Fact III, as KI contains both I- and Cl- ions.
