Draw the Lewis structure for each of the following compounds;

a) CH₃CHCHCH₂CCCH₂CH₃

Answer:

When we write this formula we get C₈H₁₂ which is a member C_nH_2n-4 group. We've never talked about this group so we need to check out the condensed formula more closely.

I've circled two different parts of the molecule, the circle in red is the location of a double bond (we saw that in part c) and the portion circled in blue is a triple bond (we saw in part b). So the Lewis structure looks like,
