a)$C_{2}$$H_{2}+$$2H_{2}$ ->$C_{2}$$H_{6}$ 

b)$CaC_{2}$ +$2H_{2}O$-> $C_{2}$$H_{2}$+ $Ca(OH)_{2}$ 

c)$C_{2}$$H_{2}$ +$2Br_{2}$-> $C_{2}$$H_{2}$$Br_{4}$ 

d)$CH_{2}$= $CH_{2}$+ $H_{2}$ ->$CH_{3}$ - $CH_{3}$ 

e)$CH_{4}$+ $Cl_{2}$-> $CH_{3}Cl$ + $HCl_{}$ 

f)$CH_{3}Cl$ +$Cl_{2}$-> $HCl+CH_{2}$$Cl_{2}$
