a)
\(n_{CO_2} = \dfrac{3,36}{22,4} = 0,15(mol)\\ n_{H_2O} = \dfrac{3,6}{18} = 0,2(mol)\\ \Rightarrow n_A = 0,2 - 0,15 = 0,05(mol)\)
Số nguyên tử Cacbon = \(\dfrac{n_{CO_2}}{n_A} = \dfrac{0,15}{0,05} = 3\)
Vậy A là \(C_3H_8\)
b) a = 0,05.44 = 2,2(gam)
c)
\(CH_3-CH_2-CH_3 + Cl_2 \xrightarrow{as} CH_3-CHCl-CH_3 + HCl\\ CH_3-CH_2-CH_3 + Cl_2 \xrightarrow{as} CH_2Cl-CH_2-CH_3 + HCl\)
