# What is the name for the compound CH_3-CH_2-CH_2-CH_2-CH_3?

Is this not $\text{n-pentane}$, ${C}_{5} {H}_{12}$, where the $n$ stands for $\text{normal}$?
$\text{n-pentane}$ is a straight-chain saturated hydrocarbon ... it has a normal boiling point of $36.1$ ""^@C, and is very combustible...
${C}_{5} {H}_{12} \left(l\right) + 8 {O}_{2} \left(g\right) \rightarrow 5 C {O}_{2} \left(g\right) + 6 {H}_{2} O + \Delta$...
