CH3-C(тройная связь)С-СH3+2HCl--> CH3-C(Cl2)-CH2-CH3

С6H6+2C3H7Cl---> 2,4(С3H7)C6H4

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

H3C-CH(CH3)-CH3 (H2SO4,t)=H3C-C(CH3)=CH2+H2

CH3-Cl+2Na+C2H5Cl=2NaCl+CH3-C2H5

CH3-CH2-C=-CH+ NaNH2=CH3-CH2-C=-CNa+NH3

CH3-C=-C-CH3+2HCl=H3C-CCl2-CH2-CH3
