Question

Un compus monoclorurat saturat cu catena aciclica are un continut in clor de 55,038%.
a) Identificati compusul clorurat.
b) Identificati trei variante de obtinere a acestui compus halogenat folosind reactii de substitutie si reactii de aditie.

Answer 1

CnH2n+1Cl - compusul clorurat
%Cl = m Cl/m compus * 100
M compus = 12n+2n+1+35,5 = 14n+36,5
55,038 = 35,5/(14n+36,5) * 100
3550 = 770,532n + 2008,887
n = 2
FM = C2H5Cl
CH2=CH2 + HCl => CH3-CH2-Cl
CH3-CH3 + Cl2 => CH3-CH2-Cl + HCl
CH3-CH2-OH + HCl => CH3-CH2-Cl + H2O
