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
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.
