Em tham khảo nha :
\(\begin{array}{l}
a)\\
CTPT:{C_x}{H_y}{O_z}\\
{n_{C{O_2}}} = \dfrac{{6,6}}{{44}} = 0,15mol\\
{n_C} = {n_{C{O_2}}} = 0,15mol\\
{n_{{H_2}O}} = \dfrac{{3,6}}{{18}} = 0,2mol\\
{n_H} = 2{n_{{H_2}O}} = 0,4mol\\
{n_A} = \dfrac{3}{{60}} = 0,05mol\\
x = \dfrac{{{n_C}}}{{{n_A}}} = \dfrac{{0,15}}{{0,05}} = 3\\
y = \dfrac{{{n_H}}}{{{n_A}}} = \dfrac{{0,4}}{{0,05}} = 8\\
z = \dfrac{{60 - 3 \times 12 - 8}}{{16}} = 1\\
\Rightarrow CTPT:{C_3}{H_8}O\\
b)\\
CTCT:\\
C{H_3} - C{H_2} - C{H_2} - OH\\
C{H_3} - CH(OH) - C{H_3}\\
c)\\
2{C_3}{H_7}OH + 2Na \to 2{C_3}{H_7}ONa + {H_2}
\end{array}\)
