1) CaC2-C2H2-C2H4-C2H4Cl2 | HCOH

2)C2H5Br-C4H10-CH2=CH~CH2~CH3-CH2=CH~CH=CH2-CH2Cl-CH-CH=CH2Cl

Answer 1

1) CaC2 + 2H2O------> Ca(OH)2 + C2H2

C2H2+ H2-------> C2H4

C2H4 +Cl2-------> C2H4Cl2 


2) C2H5Br + 2Na + C2H5Br------> C4H10 + 2NaBr

C4H10-------> C4H8 + H2

CH2=CH-CH2-CH3 -------> CH2=CH-CH=CH2 + H2

CH2=CH=CH-CH2 + Cl2------> CH2Cl-CH=CH-CH2Cl
