nparaffin
nparaffin is a term that refers to normal paraffins, which are a subclass of alkanes. Alkanes are saturated hydrocarbons, meaning they consist solely of hydrogen and carbon atoms linked by single bonds. The "n" in nparaffin signifies that the hydrocarbon chain is linear, or unbranched. In contrast to branched alkanes, nparaffins have their carbon atoms arranged in a straight sequence.
These linear hydrocarbons are typically found in petroleum and are a significant component of kerosene and
