Answer 1

Powinno być "karbid" a nie korbid.

 

CaC2 + 2H2O -------> CH≡CH + Ca(OH)2

CH≡CH + H2 -----Pt----> CH2=CH2

CH2=CH2 + H2O -----H+---->  CH3-CH2-OH

CH3-CH2-OH -----[O]-----> CH3-CHO

CH3-CHO + Ag2O ------> CH3-COOH + 2Ag↓

CH3-COOH + CH3-OH -----H2SO4-----> CH3-COO-CH3 + H2O

 

CH≡CH........etyn

CH2=CH2.....eten

CH3-CH2-OH......etanol

CH3-CHO......etanal

CH3-COOH......kwas octowy

CH3-COO-CH3.....octan metylu

 

 

Answer 2

CaC₂ (karbid) + 2 H₂O⇒ C₂H₂ (A) + Ca(OH)₂

C₂H₂ + H₂ (kat. Pt)⇒ C₂H₄ (B)

C₂H₄ + H₂O (H⁺)⇒ C₂H₅OH (C)

C₂H₅OH [O]⇒ CH₃CHO (D)

CH₃CHO + Ag₂O ⇒CH₃COOH (E) + 2 Ag

CH₃COOH + CH₃OH  (H₂SO₄)⇒ CH₃COOCH₃ (F) + H₂O

 

A-etyn

B-eten

C-etanol

D-etanal (aldehyd octowy)

E-kwas octowy

F-octan metylu
