JEE Chemistry 2023 Question with Solution

Match List I with List II:

A matching table with List I containing A. Saccharin, B. Aspartame, C. Alitame, D. Sucralose and List II containing I. High potency sweetener, II. First artificial sweetening agent, III. Stable at cooking temperature, IV. Unstable at cooking temperature.
  • A

    A-II, B-III, C-IV, D-I

  • B

    A-II, B-IV, C-I, D-III

  • C

    A-IV, B-III, C-I, D-II

  • D

    A-II, B-IV, C-III, D-I

Answer

Correct answer:B

Step-by-step solution

Standard Method

Given: A matching question on artificial sweetening agents and their properties.

Find: The correct matching between List I and List II.

From the given table:

  • Saccharin is the first artificial sweetening agent.
  • Aspartame is unstable at cooking temperature.
  • Alitame is a high potency sweetener.
  • Sucralose is stable at cooking temperature.

Therefore, the correct matching is:

A→II,B→IV,C→I,D→IIIA \to II,\quad B \to IV,\quad C \to I,\quad D \to III

So, the correct option is B.

Property-wise Identification

Given: The compounds are Saccharin, Aspartame, Alitame, and Sucralose.

Find: Which property matches each compound.

  1. Saccharin is historically known as the first artificial sweetening agent.
  2. Aspartame cannot be used for heating at high temperature because it is unstable at cooking temperature.
  3. Alitame is known as a high potency sweetener.
  4. Sucralose remains stable at cooking temperature, so it is suitable in heated foods.

Hence the final match is:

A−II,  B−IV,  C−I,  D−IIIA-II,\; B-IV,\; C-I,\; D-III

Therefore, the correct option is B.

Common mistakes

  • Confusing Aspartame with Sucralose on heating stability. Aspartame is unstable at cooking temperature, whereas Sucralose is stable. Match thermal stability carefully.

  • Assuming Saccharin is only a high potency sweetener and forgetting its historical importance. It is specifically known as the first artificial sweetening agent, so A must match II.

  • Treating Alitame and Sucralose as interchangeable sweeteners. Their key identifying properties are different, so first assign the unique facts before completing the full match.
