Draw a conventional structure corresponding to the following skeletal structure, and then name it.

Question

Accepted Answer

Don’t forget in a skeletal structure that there is a carbon at each end as well as at each vertex.

corresponds to [latex]CH_3CH_2CH_2CH_2-\overset{\overset{C H_2 -CH=CH_2}{\mid} }{C} =\underset{\underset{CH_3}{\mid}}{C} =CH_3[/latex]

The principal chain (color in the following structure) is the chain containing the greatest number of double bonds. One possible numbering scheme (red) gives the first- encountered carbons of the two double bonds the numbers 1 and 4, respectively; the other possible numbering scheme (blue) gives the first-encountered carbons of the double bonds the numbers 2 and 5, respectively. We compare the two possible numbering schemes pairwise—that is, (1,4) versus (2,5). The lowest number at first point of difference (1 versus 2) determines the correct numbering. The compound is a 1,4-hexadiene, with a butyl branch at carbon-4, and a methyl branch at carbon-5:
