How many distinct aromatic products are possible when *n*-octane is passed over a dehydrocyclisation (reforming) catalyst at high temperature and moderate pressure?

Answer: 2

Solution

Dehydrocyclisation forms a six-membered ring from six consecutive carbons of the chain, with any remaining carbons left as substituents. For *n*-octane (8 carbons), cyclising C1–C6 (or, equivalently by symmetry, C3–C8) leaves a
