а) 1. CH3-CH3 ⇒ CH2=CH2+H2 ( t, кат. Ni)
2. CH2=CH2 ⇒ CH≡СН+H2 ( t, кат. Ni)
3. 3CH≡СН ⇒ C6H6( кат. акт. уголь и температура 600 градусов)
б) 1. 2CH4 ⇒ CH2=CH2+ 3H2 ( t, кат. Ni)
2. CH2=CH2+H2O ⇒ CH3CHО (условия Hg(2+))
в) 1. C2H5OH ⇒ CH2=CH2+H2O( условия H(+) - серная кислота, t>140 градусов)
2. CH2=CH2 ⇒ CH≡СН+H2 ( t, кат. Ni)
3. CH≡СН+2НBr ⇒ CH2(Br)-CH2(Br)
Реакция получения полиэтилена :
nCH2=CH2 ⇒ (-CH2-CH2-)n (условия, t)
г) 1. CH≡СН +HCl ⇒ CH2=CH-Cl
2. nCH2=CH-Cl ⇒ (-CH2-CH(Cl)-)n
