Bài 1 :
\(CT:C_nH_{2n-6}\left(n\ge6\right)\)
\(\%C=\dfrac{12n}{14n-6}\cdot100\%=90.57\%\)
\(\Rightarrow n=8\)
\(CT:C_8H_{10}\)
Bài 2 :
\(n_{CO_2}=\dfrac{17.6}{44}=0.4\left(mol\right)\)
\(CT:C_nH_{2n+1}OH\)
\(\Rightarrow n_{ancol}=\dfrac{n_{CO_2}}{n}=\dfrac{0.4}{n}\left(mol\right)\)
\(M_A=\dfrac{7.4}{\dfrac{0.4}{n}}=\dfrac{37}{2}n\left(\dfrac{g}{mol}\right)\)
\(\Rightarrow14n+18=\dfrac{37}{2}n\)
\(\Rightarrow n=4\)
\(CT:C_4H_9OH\)
