Hôn hợp gồm:\(\left\{{}\begin{matrix}C_nH_{2n}\left(n\ge2\right)\\C_mH_{2m+2}\left(m\ge1\right)\end{matrix}\right.\)
\(C_nH_{2n}\left(0,02\right)+\left(\dfrac{3n}{2}\right)O_2-t^o->nCO_2\left(0,02n\right)+nH_2O\)
\(C_mH_{2m+2}\left(0,03\right)+\left(\dfrac{3m+1}{2}\right)O_2-t^o->mCO_2\left(0,03m\right)+\left(m+1\right)H_2O\)
Theo PTHH: Ta có: \(0,02n+0,03m=0,12\)
+ Khi \(n=2=>m=2,67\)\((loại)\)
\(n=3=>m=2\)
\(n=4=>m=1,33(loại)\)
Vậy \(CTPT:\)\(\left\{{}\begin{matrix}C_3H_6\\C_2H_6\end{matrix}\right.\)
