english: I'm sorry to hear that, so you might know that it's a very toxic substance, but you might not know that it's a very simple molecule with an unpronouncable name: it's called chlorobenzalmalononitrile.
non_english: Iko? Žao mi je što to čujem, te možda znate da je to veoma toksična supstanca ali možda ne znate da je to veoma jednostavan molekul sa neizgovorivim imenom. Zove se hlorobenzalmalononitril.
