n-Heptane can be converted into benzene by catalysts:
Correct answer: C. Al2O3, SiO2, Cr2O3
- A. Al2O3, SiO2, Fe2O3
- B. SiO2, K2O, Cr2O3
- C. Al2O3, SiO2, Cr2O3
- D. None of these
Explanation
The conversion of n-heptane to benzene is a process called aromatization. This involves the cyclic dehydrogenation of alkanes. The catalysts commonly used for this process are aluminum oxide (Al2O3), silica (SiO2), and chromium oxide (Cr2O3). These metal oxides act as Lewis acids, promoting the removal of hydrogen atoms from the alkane molecules, leading to the formation of the aromatic ring system.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
