Explanation:

When \( n \)-octane (\( C_8H_{18} \)) is subjected to catalytic dehydrocyclization in the presence of \( Cr_2O_3/Al_2O_3 \) at 873 K:

The process involves the formation of cyclic products.
Only products with un-rearranged structures are considered, meaning the linear carbon chain is used to form the rings without rearrangement.
Cyclic products are formed by dehydrogenation, leading to cyclization with no changes to the linear sequence of carbon atoms.

Possible Cyclic Products:

Cyclohexane: A 6-membered ring with two methyl groups on adjacent carbons.
Methylcyclopentane: A 5-membered ring with a methyl group attached to one of the ring carbons.
Cyclobutane: A 4-membered ring with additional alkyl chains attached.

Answer: There are 3 possible cyclic products for n-octane under the given conditions.
