Question

Se considera schema de reactii 6.3, unde compusul b este o substanta insolubila in apa cu compozitia procentuala de masa: 67,08%Ag; 29,81%C; 3,1%H. Sa se identifice substantele din schema. Ajuutoor!

Answer 1

b: C : 29,81% : 12 = 2,484    | : 0,621 = 4
    H :  3,1%    : 1 = 3,1            | : 0,621 = 5
   Ag : 67,08   : 108 = 0,621   | : 0,621 = 1    b = C4H5Ag ⇒ B = 1butina
A = CH2=CH-CH2-CH2 :   a= CH2Cl-CHCl-CH2-CH3  c = CH2=CCl-CH2-CH3
d = CH3-CCl2-CH2-CH3;  e = CH3-CO-CH2-CH3; f = CH3-CHCl-CH2-CH3;
C = CH3-CH=CH-CH3 ;  g = CH3-CHCl-CHCl-CH3;
D = CH3-C≡C-CH3 ;  h = CH3-CH=C(OH)-CH3 
i = NaC≡CNa ;  j = NaC≡C-CH3
