Answer:

Well, it's an olefin with a #C=C# bond.......

Explanation:

And we could draw the molecular formula as.......

#H_3stackrel(1)C-stackrel(2)CH=stackrel(3)CHstackrel(4)CH_2stackrel(5)CH_2stackrel(6)CH_2stackrel(7)CH_2stackrel(8)CH_3#

At #stackrel(2)C# we insert the olefinic bond, the so-called site of unsaturation. And we note that molecule would support geometric isomerism in that the double bond generates cis and trans isomers about #C_2#, #C_3#.

What would we call......

#H_2stackrel(1)C=stackrel(2)CH_2stackrel(3)CH_2stackrel(4)CH_2stackrel(5)CH_2stackrel(6)CH_2stackrel(7)CH_2stackrel(8)CH_3#

Would this molecule be isomeric?
