huynh post cách thứ 2 nhé:
CH4 +CL2 >CH3CL +HCL
2CH3CL +Na >C2H6 +NACL
C2H6 +CL>C2H5CL>C4H10
CH3-CH2-CH2-CH3+Cl2--->CH3-CH2-CHCl-CH3+HCl
CH3-CH2-CHCl-CH3---->CH3-CH=CH-CH3+HCL
CH3-CH=CH-CH3+Cl2-->CH3-CH=CH-CH2Cl+HCl
CH3-CH=CH-CH2Cl+H2-->CH3-CH2-CH2-CH2Cl
CH3-CH2-CH2-CH2Cl+KOH--->CH3-CH2-CH2-CH2OH+KCl
2CH3-CH2-CH2-CH2-OH--->CH3-CH2-CH2-CH2-O-CH2-CH2-CH2-CH3
