Write name and structural formulae of all isomers of octyne?

Asked by Rajeev Kumar | 22nd Nov, 2010, 12:00: AM

Expert Answer:

Dear Student
 
Octyne molecular formula is C8H14
Position isomers: The position of doublebond forms following isomers.
 
CH3CH2CH2CH2CH2CH2C≡CH 1-octyne
 
CH3CH2CH2CH2CH2C≡CCH3 2-octyne

CH3CH2CH2CH2C≡CCH2CH3                        3-octyne
 
CH3CH2CH2C≡CCH2CH2CH3      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=CH2      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.
