Paraffins are best described as which type of hydrocarbons?

• A. Aromatic hydrocarbons
• B. Saturated hydrocarbons
• C. Unsaturated hydrocarbons
• D. Heterocyclic compounds

Answer: (B)

Paraffins are saturated hydrocarbons, meaning they are alkanes with only single bonds between carbon atoms and the maximum number of hydrogen atoms attached to them. This saturation sets them apart from aromatic hydrocarbons (which have ring structures with delocalized electrons), unsaturated hydrocarbons (which contain double or triple bonds), and heterocyclic compounds (which include atoms other than carbon in the ring). Examples like methane, ethane, propane, and butane illustrate the simple, fully hydrogenated links of carbon in paraffins. General formula for these compounds is CnH2n+2.
