JEE Chemistry 2023 Question with Solution

Given: The solution discusses trends of boiling point and density for halogenated compounds.

Find: Which listed set of statements is correct.

From the solution:

1. Boiling point increases with molecular mass and stronger intermolecular forces.
2. For halogenated compounds, larger halogens generally increase boiling point because of stronger van der Waals forces.
3. Density increases with molecular mass and atomic size.
4. For halogens, the trend stated is:

$$\text{Cl} < \text{Br} < \text{I}$$

for these properties in the relevant context.

The extracted explanation explicitly states:

• (A) is correct.
• (B) is incorrect.
• (C) is correct.
• (D) is consistent with the general trend.

Hence the correct set is:

$$(A), (C), \text{ and } (D) \text{ only}$$

This matches option A in the solution, even though the raw option text labeled as choice A is different from the answer key. Therefore, there is a discrepancy between the listed options/correct-answer field and the solution.

the correct option is A.
