JEE Chemistry 2025 Question with Solution

Given below are two statements:

Image showing Statement I and Statement II with organic structures involving diethylamino and chloroalkyl compounds, comparing alkaline hydrolysis rate and intramolecular substitution involving lone pair on nitrogen.
  • A

    Both Statement I and Statement II are incorrect

  • B

    Both Statement I and Statement II are correct

  • C

    Statement I is correct but Statement II is incorrect

  • D

    Statement I is incorrect but Statement II is correct

Answer

Correct answer:D

Step-by-step solution

Standard Method

Given: Two statements are provided in the figure.

Find: Which statement is correct.

The solution concludes that the correct option is D.

From the extracted working:

  1. Statement I is taken as incorrect.
  2. Statement II is taken as correct.

Conclusion: Therefore, Statement I is incorrect but Statement II is correct. Hence, the correct option is D.

Note: The available the solution appears unrelated to the image-based question content and discusses speed of sound and bulk modulus. However, the solution explicitly marks the correct option as D, so the answer is taken as D.

Common mistakes

  • Ignoring the image-based chemical structures and trying to infer the answer only from the option wording. This is incorrect because the truth of each statement depends on the specific structures shown. Always inspect the diagram carefully before evaluating Statement I and Statement II.

  • Assuming the explanatory text in the solution matches the question. Here, the working discusses sound and bulk modulus, which is unrelated to the displayed organic chemistry statements. Do not use unrelated reasoning; rely only on matching solution content or the explicitly marked correct option.
