Question

1. Construa as seguintes cadeias carbónicas insaturadas.

e) hept-2,4-dieno
a) pent-1,3-dieno
c) oct-2,5-dina
d) but-3-eno
b) hex-1-ino​

Answer 1

Cadeia carbônica insaturada

a) pent-1,3-dieno : H₂C=CH-CH=CH-CH₃

b) hex-1-ino​ : HC≡C-CH₂-CH₂-CH₂-CH₃

c) oct-2,5-diino : H₃C-C≡C-CH₂-C≡C-CH₂-CH₃

d) but-3-eno (incorreto) : but-1-eno : H₃C-CH₂-CH=CH₂

e) hept-2,4-dieno : H₃C-CH=CH-CH=CH-CH₂-CH₂-CH₃
