Pentadiene - Wikipedia
网页In organic chemistry, pentadiene is any hydrocarbon with an open chain of five carbons, connected by two single bonds and two double bonds. All those compounds have the same molecular formula C 5 H 8. The inventory of pentadienes include: 1,2-pentadiene, or ethyl allene, H 2 C=C=CH−CH 2 −CH 3. [1] 1,3-pentadiene, H 2 C=CH−CH=CH−CH 3 ...

8: Conjugated compounds and aromaticity - Chemistry LibreTexts
网页2021年12月12日 · To explain how conjugated systems behave differently from non-conjugated systems we will compare 1,3-pentadiene (which is conjugated) and 1,4 pentadiene (which is not conjugated). To recognize the differences between the two, let us look at the orbitals that are involved in the \(\pi\) system bonding.
