Answer 1

a. C₂H₂ \(\underrightarrow{t^o,xt}\)CH₂=CH-C≡CH

CH₂=CH-C≡CH \(\xrightarrow[to]{PdCO_3}\)CH₂=CH-CH=CH₂

nCH₂=CH-CH=CH₂\(\underrightarrow{t^o,xt}\) (-CH_2-CH=CH-CH₂-)_n

b. C₂H₄ + H2O \(\underrightarrow{t^o,xt}\) C₂H₅OH

2C₂H₅OH \(\underrightarrow{t^o,xt}\) CH₂=CH-CH=CH₂ + H2O

nCH₂=CH-CH=CH₂\(\underrightarrow{t^o,xt}\) (-CH_2-CH=CH-CH₂-)_n

c. 6nCO₂ + 5nH₂O _{\(\underrightarrow{Quang,hợp}\)} (C₆H₁₀O₅)_n + 6nO₂

(C₆H₁₀O₅)_n + H2O \(\underrightarrow{t^o,xt}\) nC₆H₁₂O₆

C₆H₁₂O₆\(\underrightarrow{lên,men}\)2C₂H₅OH + 2CO₂

2C₂H₅OH \(\underrightarrow{t^o,xt}\) CH₂=CH-CH=CH₂ + H₂O
