# How does "propionaldehyde" differ from "acetone"?

$\text{Propanone}$, more commonly referred to as $\text{acetone}$, has a structural formula ${\text{H"_3"CC(=O)CH}}_{3}$. Isomeric $\text{propanal}$ has the same $\text{C"_3"H"_6"O}$ molecular formula but a structure of $\text{H"_3"CCH"_2"C(=O)H}$.
