Styrene yog ib qho organic compound.Nws yog monomer ntawm polystyrene.polystyrene tsis yog ib qho khoom xyaw ntuj.Polymer ua los ntawm styrene yog hu ua polystyrene.Nws yog ib tug hluavtaws compound.Nyob rau hauv no compound muaj ib tug benzene nplhaib.Yog li ntawd, nws tseem hu ua ib qho aromatic compound.Hauv tsab xov xwm no, peb tau hais txog tag nrho cov ntsiab lus tseem ceeb thiab cov ntsiab lus ntawm styrenes zoo li styrene mis, nws siv, synthesis ntawm styrene, styrene qauv, thiab nws cov khoom.
Styrene Formula
Cov qauv styrene qauv yog C6H5CH = CH2.Cov tshuaj styrene yog C8H8.Tus lej sau nyob rau hauv subscript ntawm C sawv cev rau tus naj npawb ntawm carbon atoms thiab tus lej sau nyob rau hauv subscript ntawm H sawv cev rau tus naj npawb ntawm hydrogen atoms.C6H5 sawv cev rau lub nplhaib benzyl thiab CH = CH2 sawv cev rau ob txoj hlua carbon alkene.Lub npe IUPAC ntawm styrene yog Ethenylbenzene.Nyob rau hauv cov qauv styrene, ib lub nplhaib benzene yog txuas mus rau vinyl pawg los ntawm covalent bonding.Plaub pi bonds muaj nyob rau hauv cov qauv styrene.Cov pi bonds yog hloov pauv nyob rau hauv styrene.Raws li qhov kev npaj ntawm resonance phenomena tshwm sim nyob rau hauv lub styrene qauv.Lwm yam tshaj li cov pi bonds yim sigma bonds kuj muaj nyob rau hauv cov qauv styrene.Cov sigma bonds tam sim no nyob rau hauv lub styrene yog tsim los ntawm lub taub hau-on overlapping s orbitals.Cov pi bonds yog tsim los ntawm lateral overlapping ntawm p orbitals.
