A. 19,42.
B. 26,21.
C. 13,59.
D. 38,84.
A
\(0,06\left\{ \begin{array}{l} X:{C_n}{H_{2n}}:x\\ Y,Z:{C_m}{H_{2m + 2 - 2k}}:y \end{array} \right. \to \left\{ \begin{array}{l} C{O_2}:0,15\\ {H_2}O \end{array} \right.\)
BT O: \(2{{n}_{{{O}_{2}}}}=2{{n}_{C{{O}_{2}}}}+{{n}_{{{H}_{2}}O}}\to {{n}_{{{H}_{2}}O}}=0,13\text{ mol}\)
\({{\text{n}}_{Y,Z}}=\frac{{{n}_{C{{O}_{2}}}}-{{n}_{{{H}_{2}}O}}}{k-1}\to y\left( k-1 \right)=0,02\)
TH: \(k=2\to y=0,02,\text{ }x=0,04\)
BT C: 0,04.n+0,02.m=0,15
Với \(n=2\to m=3,5\)
\( \to 0,06\left\{ \begin{array}{l} X:{C_2}{H_4}:0,04\\ {C_3}{H_4}:a\\ {C_4}{H_6}:b \end{array} \right. \to \left\{ \begin{array}{l} a + b = 0,02\\ 3a + 4b = 0,15 - 0,04.2 \end{array} \right. \to \left\{ \begin{array}{l} a = 0,01\\ b = 0,01 \end{array} \right.\)
\(%{{m}_{{{C}_{3}}{{H}_{4}}}}=19,42%\).
