First, you have drawn heptene since you have 7 carbons in a row.
Hexene is a six carbon chain. Draw that and put the double bond at the first carbon. That's the 1.
CH2=CH-CH2-CH2-CH2-CH3
Begin numbering so that the longest chain has the double bond AND that the double bond is the smallest number. Then on carbon #2, replace the H with a CH3. That will be 2-methyl-1-hexene. You may want to count the bonds. Each C should have 4 bonds, each H should have 1 bond.
I have to draw the compound 3 methyl 1-hexene.
This is what I've got:
CH
CH=CH-CH-CH-CH-CH-CH
I know there should be some numbers attached to the CH's, but I dont' know where they should be and what they should be. What are the rules concerning numbers? How do you know where to put them? Thank you for your help!
