Problemaaaa 1, va rog mult!!!

Answer 1

A : R-CH(NH2)-COOH      32·100/M = 42,66    ⇒ M = 75g/mol 
75 - 45 - 16 = 14  ⇒ R-CH ≡ CH2     A : H2N-CH2- COOH 
B :14·100/M = 10, 687 ⇒ M = 131 g/mol
131 - 45 - 16 = 70    ⇒ R-CH  ≡  -C5H10-     B : C6H13O2N
B: CH3 - CH2 - CH*(CH3) - C*H(NH2)- COOH 
HOOC-CH2-NH2 + HCl ⇒ HOOC-CH2-NH3]⁺Cl⁻ + NaOH = 
= Na⁺⁻OOC-CH2-NH3]⁺Cl⁻
HOOC-CH2-NH2+ C6H5-CO - Cl  = HOOC - CH2- NH-CO-C6H5 + HCl
