If each of the following represents an alkane, and a carbon atom is located at each vertex with the proper number of hydrogen atoms also bonded to it, which one is the most reactive?
E)They are all equally reactive since they are all alkanes.

The most reactive alkane will have the most unstable or strained bonds. Looking at the structures, option D has a cyclopropane ring which is highly strained and is the most reactive among the given options. The other options are all straight-chain alkanes which have less strain and are relatively stable, therefore less reactive.
