Question

What is the major product when n-hexane is passed over a Pt/$Al_2O_3$ catalyst at high temperatures and pressures?

Prashant Kotian · Accepted Answer

Correct answer: B. This is an aromatization/reforming reaction. Straight-chain alkanes like n-hexane undergo cyclization to cyclohexane, followed immediately by dehydrogenation (-3H2) to yield highly stable benzene.
