Lewis structure of acrolein.
Acrolein is a clear or yellow liquid with a burnt, sweet, pungent odor. Most people begin to smell acrolein in air at concentrations of 0.25 parts acrolein per million parts of air (ppm). It ignites and burns easily in air. Acrolein changes into a vapor much faster than water does at normal temperatures. The change of acrolein from a liquid to ...
