Adjacent carbons, these carbons no longer have the necessary four bonds, and accomplish that by making double bonds or alkenes instead of alkanes. The structures below are examples where the doubled lines represent the double bonds. For each of the following pairs of compounds, make a model of both compounds at the same time, and then compare them to see if they are the same or different (circle the correct choice). (Some are pretty trivial - take shortcuts at your own risk)

Pair B:
