2) C2H6 +Br2----- C2H5Br+ HBr
3) C2H5Br+2Na---- C2H5+ Na2Br
4) C2H5-H2----- C2H3
5) C2H3 + Cl2---- C2H2Cl+HCl
6) C2H2Cl+KOH---- C2H2 +KCl+H2O 

Answer 2

c2h4+h2---c2h6
c2h6+br2---c2h5br+hbr
2c2h5br+2na---c4h10+2nabr
c4h10---ch2=ch-ch2-ch3+h2
ch2=ch-ch2-ch3+cl2--- ch2cl-chcl-ch2-ch3

ch2cl-chcl-ch2-ch3+koh---изопентен+кcl+h2o
