1) 3С2H2=C6H6
C6H6+Cl2=C6H5Cl+HCl
C6H5Cl+NaOH=C6H5OH+NaCl
C6H5OH+NaOH=C6H5ONa+H2O
2)CH3-CH2-CH3=CH2=CH-CH3+H2
CH2=CH-CH3+HOH=CH3-CHOH-CH3
CH3-CHOH-CH3+HCl=CH3-CHCl-CH3+H2O
CH3-CHCl-H3+NaOH=CH2=CH-CH3+NaCl+H2O
3) CH2=CH-CH3=CH=-C-CH3+H2
CH=-C-CH3+HOH= CH3-CO-CH3
CH3-CO-CH3+H2=CH3-CHOH-CH3
CH3-CHOH-CH3=CH2=CH-CH3+H2O
4) CH3-CH3=CH2=CH2+H2
CH2=CH2=CH=-CH+H2
3CH=-CH=C6H6
C6H6+CH3Cl=C6H5CH3+HCl
