Question

Statement-1 : Arginine `(I)`, is the most basic out of twenty common amino acids
`H_(2)N-underset(underset(NH)(||))(C)-NH-CH_(2)CH_(2)CH_(2)- underset(underset(NH_(2))(|))(CH)-COOH`.
Statement-2 : Arginine contains guanidine group whose protonated cation is highly stable due to `+m` effect.
A. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1
B. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-1
C. STATEMENT-1 is true, STATEMENT-2 is false
D. STATEMENT-1 is false, STATEMENT-2 is true

Answer 1

Correct Answer - A
`underset("guanidino group")ubrace(underset(underset(NH)(||))(H_(2)N-C-NH))-CH_(2)CH_(2)CH_(2)-underset(underset(NH_(2))(|))(CH)-COOH`.
