How are alkanes used in real life?

Aromatization is the procedure of converting an aliphatic compound into a non aromatic compound using a catalyst. This is usually done through the pathwya of techniques like dehydrogenation where a non aromatic compound is converted into an aromatic compound. Examples: converting cyclohexane to benzene, androgens to estrogens, etc. The final product always contains a benzene-like ring structure which follows Hückel's rule.

This happens due to the fact that they possess strong C-C and H-H bonds which are non-polar sigma bonds and cannot be broken easily. Also, they lack polar functional groups and are saturated hydrocarbons. These properties combined make them less reactive overall.
