Saturated hydrocarbons with the general formula CnH2n+2 are commonly known as what?

• A. Paraffins or alkanes
• B. Naphthenes/Cycloalkanes
• C. Aromatic compounds
• D. Kerogen

Answer: (A)

These are alkanes, the saturated hydrocarbons that follow the formula CnH2n+2. Saturation means all carbon–carbon bonds are single bonds, so each carbon atom forms four single bonds in total. In an acyclic (non-ring) chain, this structure leads to the hydrogen count of 2n+2 for n carbon atoms, which is why every member of this family fits that formula. Common examples include methane (one carbon), ethane (two carbons), propane, and butane. Other groups don’t match that formula. Cycloalkanes or naphthenes have rings; the ring structure reduces the number of hydrogens, giving a general formula closer to CnH2n rather than CnH2n+2. Aromatic compounds contain conjugated double bonds in ring systems and also do not follow the CnH2n+2 pattern. Kerogen is a complex, variable mixture of organic material, not a single hydrocarbon class with a universal formula.
