Match the List-I with List-II List-I Amino acid List-II Positive reaction/Test for functional group present in side chain of amino acid A. Glutamine I. Hinsberg's test B. Lysine II. Neutral FeCl ₃ test C. Tyrosine III. Ceric ammonium nitrate test D. Serine IV. Hoffman bromamide degradation Choose the correct answer from the options given below:

Options

  1. AA-IV, B-II, C-I, D-III
  2. BA-IV, B-I, C-II, D-III
  3. CA-III, B-II, C-I, D-IV
  4. DA-IV, B-I, C-III, D-II

Correct answer

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

Step-by-step solution

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 FeCl ₃ 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 corr
