Un derivat monoclrurat cu formula moleculara CnH2n-1Cl are un continut masic de 46,4% clor.Determina formula moleculara a compusilor si toti izomerii sai. :)
Multumesc anticipat! :)


Răspuns :

-derivatul clorurat provine dintr-o alchena
M,derivat= [12n gC+(2n-1)gH+35,5gCl]/mol
14n+34,5  g compus.........35,5gCl
100g.................................46,4g
35,5x100= 46,4(14n+34,5)
n=3---> CH2=CH-CH3       PROPENA
