formula moleculara A = (CnH2n+2O)a, unde a = M.f.n/M.f.b.
=> CnaH2na+2aOa
44,8/22,4 = 2 moli CO2
64 g 2 moli
CnaH2na+2aOa + naO2 --> naCO2 + (n+1)aH2O
miu na
=> 64na = 2miu
=> 64na = 28na+36a
=> 36na = 36a => n = 1
=> (CH4O)a,
daca a = 1 => CH3OH DA
daca a = 2 => C2H7O2 NU
=> A = CH3OH, alcoolul metilic
C-O = polara
H-O = polara
C-H = polara
