A chemist has 4 samples of artificial sweetener A , B , C and D . To identify these samples, he performed certain experiments and noted the following observations:
(i) A and D both form blue-violet colour with ninhydrin.
(ii) Lassaigne extract of C gives positive AgNO3 test and negative Fe4[Fe(CN)6]3 test.
(iii) Lassaigne extract of B and D gives positive sodium nitroprusside test. Based on these observations which option is correct?
(i) A and D both form blue-violet colour with ninhydrin.
(ii) Lassaigne extract of C gives positive AgNO3 test and negative Fe4[Fe(CN)6]3 test.
(iii) Lassaigne extract of B and D gives positive sodium nitroprusside test. Based on these observations which option is correct?
- a)A : Aspartame; B : Saccharin; C : Sucralose; D : Alitame
- b)A : Alitame; B : Saccharin; C : Aspartame; D : Sucralose
- c)A : Saccharin; B : Alitame; C : Sucralose; D : Aspartame
- d)A : Aspartame; B : Alitame; C : Saccharin; D : Sucralose
Correct answer is option 'A'. Can you explain this answer?

A− Aspartame
B− Saccharine
C− Sucralose
D− Alitame
(i) A & D give positive test with ninhydrin because both have free carboxylic and amine groups.
(ii) C form precipitate with AgNO3 in the Lassaigne extract of the sugar because it has chlorine atoms.
(iii) B & D give positive test with sodium nitroprusside because both have sulphur atoms
(ii) C form precipitate with AgNO3 in the Lassaigne extract of the sugar because it has chlorine atoms.
(iii) B & D give positive test with sodium nitroprusside because both have sulphur atoms

Observations:
- A and D both form blue-violet colour with ninhydrin.
- Lassaigne extract of C gives positive AgNO3 test and negative Fe4[Fe(CN)6]3 test.
- Lassaigne extract of B and D gives positive sodium nitroprusside test.
Analysis:
- From the first observation, we can conclude that A and D contain amino groups because ninhydrin reacts with amino acids to form a blue-violet colour.
- The second observation indicates that C contains sulfur because it gives a positive AgNO3 test, which confirms the presence of sulfur.
- The third observation suggests that B and D contain a carbonyl group because they give a positive sodium nitroprusside test, which indicates the presence of a carbonyl compound.
Conclusion:
- Aspartame (A) is known to contain an amino group, which explains the reaction with ninhydrin.
- Sucralose (C) contains sulfur, as indicated by the positive AgNO3 test.
- Saccharin (B) and Alitame (D) both contain a carbonyl group, which explains the positive sodium nitroprusside test.
Therefore, based on the observations and analysis, the correct identification of the samples is:
A : Aspartame
B : Saccharin
C : Sucralose
D : Alitame
- A and D both form blue-violet colour with ninhydrin.
- Lassaigne extract of C gives positive AgNO3 test and negative Fe4[Fe(CN)6]3 test.
- Lassaigne extract of B and D gives positive sodium nitroprusside test.
Analysis:
- From the first observation, we can conclude that A and D contain amino groups because ninhydrin reacts with amino acids to form a blue-violet colour.
- The second observation indicates that C contains sulfur because it gives a positive AgNO3 test, which confirms the presence of sulfur.
- The third observation suggests that B and D contain a carbonyl group because they give a positive sodium nitroprusside test, which indicates the presence of a carbonyl compound.
Conclusion:
- Aspartame (A) is known to contain an amino group, which explains the reaction with ninhydrin.
- Sucralose (C) contains sulfur, as indicated by the positive AgNO3 test.
- Saccharin (B) and Alitame (D) both contain a carbonyl group, which explains the positive sodium nitroprusside test.
Therefore, based on the observations and analysis, the correct identification of the samples is:
A : Aspartame
B : Saccharin
C : Sucralose
D : Alitame
