Question

CaC2->C2h2->CH3OH->C2H5OH->C2H4->C2H5->C2H5OH->C4H6->C4H8Br2

Answer 1

1)CaC2+2HOH=Ca(OH)2+C2H2

2)2C2H2+5O2=4CO2+2H2O

CO2+C=2CO

CO+2H2=CH3OH

3)CH3OH+HCl=CH3Cl+H2O

2CH3Cl+2Na=2NaCl+C2H6

CH3-CH3+Cl2=CH3-CH2Cl+HCl

CH3-CH2Cl+KOH=CH3-CH2OH +KCl

3)C25OH=C2H4+H2O

 

4)C2H4+H2=C2H6

5)C2H6+Cl2=C2H5Cl+HCl

C2H5Cl+NaOH=C2H5OH+NaCl

C2H5OH+HCl=C2H5Cl+H2O

2C2H5Cl+2Na=2NaCl+C4H10

C4H10=C4H6+2H2

C4H6+2HBr=C4H8Br2
