Question

Составьте уравнения реакций, при помощи которых можно осуществить следующие превращения: CH4 → C2H2 → CH3 -- COH → CH3 -- CH2 -- OH → CH3 -- CH2 -- Br → C2H4 →CH3 --CH2 -- OH → CH3 -- COH → CH3 -- COOH → CH3 -- COONa

Answer 1

2CH₄ --> C₂H₂ + 3H₂ (t)
C₂H₂ + H₂O --> CH₃COH (Kt=HgSO₄,t)
CH₃COH +H₂ --> CH₃CH₂-OH
CH₃CH₂-OH + HBr --> CH₃CH₂-Br + H₂O
CH₃CH₂-Br ---> CH₂=CH₂ + HBr
CH₂=CH₂ + H₂O --> CH₃CH₂-OH
CH₃CH₂-OH + CuO --> CH₃COH + H₂O + Cu
CH₃COH + Ag₂O --> CH₃COOH + 2Ag (NH₃,t)
2CH₃COOH + 2Na --> 2CH₃COONa + H₂

Answer 2

Formation of C2H2 from CH4:

The reaction equation for the formation of C2H2 (acetylene) from CH4 (methane) can be represented as follows:

CH4 → C2H2 + 2H2

Formation of CH3- from C2H2:

The reaction equation for the formation of CH3- (methyl anion) from C2H2 (acetylene) can be represented as follows:

C2H2 + 2Na → 2CH3- + 2Na+

Formation of CH3- and COH from CH3-:

The reaction equation for the formation of CH3- (methyl anion) and COH (formaldehyde) from CH3- can be represented as follows:

CH3- + H2O → CH3- + COH

Formation of CH3-, CH2-, and OH from CH3-:

The reaction equation for the formation of CH3- (methyl anion), CH2- (methylene anion), and OH- (hydroxide ion) from CH3- can be represented as follows:

CH3- + CH2Br → CH3- + CH2- + Br-

Formation of C2H4 from CH2- and Br:

The reaction equation for the formation of C2H4 (ethylene) from CH2- (methylene anion) and Br- (bromide ion) can be represented as follows:

CH2- + Br- → C2H4

Formation of CH3-, CH2-, and OH from CH3- and OH:

The reaction equation for the formation of CH3- (methyl anion), CH2- (methylene anion), and OH- (hydroxide ion) from CH3- and OH- can be represented as follows:

CH3- + OH- → CH3- + CH2- + OH-

Formation of CH3-, COH, and COOH from CH3- and COH:

The reaction equation for the formation of CH3- (methyl anion), COH (formaldehyde), and COOH (formic acid) from CH3- and COH can be represented as follows:

CH3- + COH → CH3- + COH + COOH

Formation of CH3-, COH, and COONa from CH3- and COOH:

The reaction equation for the formation of CH3- (methyl anion), COH (formaldehyde), and COONa (sodium formate) from CH3- and COOH can be represented as follows:

CH3- + COOH → CH3- + COH + COONa
