Question:

Column-I Column-II
(A) Tyrosine (P) Essential amino acids
(B) Serin (Q) Ceric Ammonium Nitrate
(C) Tryptophane (R) Neutral FeCl3
(D) Proline (S) Carbylamine Test - Negative
Select the correct set of answer.

A-Q, B-R, C-S, D-P

A-R, B-Q, C-P, D-S

A-R, B-P, C-Q, D-S

A-S, B-Q, C-P, D-R

Solution:

Correct option is A. A-R, B-Q, C-P, D-S
Solution:- (A) A−R, B−Q, C−P, D−S
(A) Tyrosine → Tyrosine gives neutral FeCl3 test
(B) Serin → It contains alcohol group (−OH) and thus will give positive test on reaction with Ceric ammonium nitrate
(C) Tryptophane → An essential amino acids needed for normal growth in infants and for nitrogen balance in adults
(D) Proline → It contains secondary amine group and thus does not give positive carbytl amine test.
