Correct answer
BA-IV, B-I, C-II, D-III
Step-by-step explanation
Glutamine contains an amide group in its side chain, which gives a positive Hoffmann bromamide degradation test. Thus, A matches IV.
Lysine contains a primary amine group in its side chain, which gives a positive Hinsberg's test. Thus, B matches I.
Tyrosine contains a phenolic hydroxyl group in its side chain, which gives a positive neutral test. Thus, C matches II.
Serine contains an alcoholic hydroxyl group in its side chain, which gives a positive ceric ammonium nitrate test. Thus, D matches III.
The correct match is A-IV, B-I, C-II, D-III.
Answer: A-IV, B-I, C-II, D-III
Lysine contains a primary amine group in its side chain, which gives a positive Hinsberg's test. Thus, B matches I.
Tyrosine contains a phenolic hydroxyl group in its side chain, which gives a positive neutral test. Thus, C matches II.
Serine contains an alcoholic hydroxyl group in its side chain, which gives a positive ceric ammonium nitrate test. Thus, D matches III.
The correct match is A-IV, B-I, C-II, D-III.
Answer: A-IV, B-I, C-II, D-III
