Write name and structural formulae of all isomers of octyne?

Dear Student

 

Octyne molecular formula is C₈H₁₄

Position isomers: The position of doublebond forms following isomers.

 

CH₃CH₂CH₂CH₂CH₂CH₂C≡CH 1-octyne

 

CH₃CH₂CH₂CH₂CH₂C≡CCH_{3 2-octyne}

CH₃CH₂CH₂CH₂C≡CCH₂CH₃                        3-octyne

 

CH₃CH₂CH₂C≡CCH₂CH₂CH_{3      4-octyne}

 

2.Chain isomers

 

CH₃CH₂CH₂C≡CCH(CH₃)_{2   2-methyl-3-heptyne}

 

(CH₃)₂CHC≡CCH(CH₃)_{2      2,5-dimethyl-3-hexyne}

 

Similarly you can draw more structural isomers. 

 

3. Functional group isomers.

CH₂=CHCH₂CH₂CH₂CH₂CH=CH_{2      1,7-octadiene}

 

Similarly other functional group isomers can be drawn, by changing the positions of the double bonds.

 

                    

 

 

We hope that clarifies your query.
