What is the name of the molecule shown below?

Nov 7, 2016

The compound shown is actually an alkene , having only one saturation. So this is the bond line notation of alkene having 8 Carbon atoms .

Explanation:

A double bond gets the first preference in a hydrocarbon.
So, numbering starts from the extreme left carbon atom .

It should be noted that the saturation is in the first and second carbon atoms. But, while mentioning the position of the double the lowest magnitude of locator should be used.

So, the condensed form of the molecule is :
${H}_{2} C = C H - C {H}_{2} - C {H}_{2} - C {H}_{2} - C {H}_{2} - C {H}_{2} - C {H}_{3}$.

It has 8 (oct) carbon atoms and one double bond (ene).

So, the name is :
Oct $- 1 -$ene , or rather Octene .

Hope it Helps :)
